Why is my 12 volt battery not working?

I’m seeing 12 volt power leaving the battery, but NO 12 volt power is at the invertor / convertor inside the camper. This ruled out a bad invertor / convertor and led me to believe we had a cut wire somewhere… However the solution was much easier and cost nothing to fix… with that said check out the video for the solution…

How are batteries connected in a series connection?

In a series connection, the + contact of a battery is connected with the – contact of another battery, thus forming one “new” battery. In the two ends of this battery (from now on called battery bank) there are one + and one – contact unconnected. These two contacts are the positive and negative pole of the bank.

How is a power adapter connected to a battery?

The port for the power adapter will also be connected through a relay to the DC-IN of the motherboard and to the charging port of the battery. When the adapter is present the adapter relay is closed and the battery relay is opened. When no adapter is present it closes the battery relay and opens the adapter relay.

Which is the National Electrical Code for DC batteries?

Can a battery be changed from AC to DC?

Wall outlet power is generally alternating current, or ‘AC’. Batteries are direct current ‘DC’ and only push the current in one direction. An AC to DC power supply can change AC wall power to DC power.

Can a battery be charged with a DC power supply?

Batteries are direct current ‘DC’ and only push the current in one direction. An AC to DC power supply can change AC wall power to DC power. Many common devices that have batteries (laptops, smart phones, etc) only accept DC power. They use a AC to DC power supply to allow us to charge the device by plugging it into the wall.

Can a dirty battery impede a power converter?

Dirty batteries can seriously impede the charging circuit and can and will draw voltage directly off the battery. Good luck. We have a 2009 Forest River Salem Travel Trailer that is parked year round at a resort wtih 30 amp service.

What happens when you run a 12V power inverter?

This is what happens when you run your AC powered appliance connected to a 12v power inverter with a deep cycle marine battery and battery charger connected. This is what I would do if I thought the power was going to go off. This is a true UPS setup. The light you see is a 500 watt halogen load. The inverter is a Harbor Freight 750 watt.

What does it mean when your RV 12 volt is not working?

In fact, RV 12 Volt system not working is considered to be one of the most frustrating issues RVers may experience. Fortunately, you don’t have to be an expert to determine the cause and possibly carry out repair when your RV 12-Volt system breaks down.

What to do if your 12 volt battery is not charging?

With the shore cord plugged in take a VDC reading at the battery to see if it is charging. It should be about 13.6 VDC or so. Unplug the power source and then take a reading at the outgoing leads from the fuses for your circuits. If you don’t have any power there then the converter is bad and needs to be replaced.

What happens when a 12 volt light does not work?

Your RV relies on its 12-volt electrical system to power like your water pump, lights, and other necessities. When it doesn’t work, it’s a major problem.

Can a 12 volt power converter run without a battery?

Lastly, check the batteries a properly working converter should run the entire 12 volt system even without a battery (though it’s not recommended due to the tendency of converters to let transient AC voltage through, the battery acts like a “filter”).

Why is my 12 volt generator not working?

The problem could be: 1 Dead batteries 2 Undercharged batteries 3 No water in the batteries 4 Loose battery connections 5 A burned-out fuse on the inverter/converter 6 Loose connections on the inverter/converter 7 A tripped breaker 8 Unplugged from shore power

Your RV’s 12-volt system runs off of the batteries, and if they are dead, damaged, or undercharged, that could stop your 12-volt system from working. Likewise, your inverter/converter is also essential to your 12-volt electrical system, and that could be the source of the problem.

Is it safe to use a 12V battery?

However, it’s really current that you feel and that shocks you, not voltage. So when we say that 12 V is safe, we’re making implicit assumptions about the resistance of your skin. Electrically, you’re basically a bag of salt water. Your insides have low resistivity, but the skin has much higher resistance.

Why are the batteries on my RV not working?

The problem could be: The obvious solution is to recharge the batteries immediately. Unfortunately, if your batteries are completely drained, they may no longer effectively hold a full charge. If your batteries have previously completely drained, they may no longer hold a complete charge.

Can a 12V battery run off the Charger?

In most vans the 12v equipment will run off either the battery or the charger unit, although in many, running it off just the charger will not do the charger any good and you get issues like the lights dimming when you run the pump. Woodentop has it spot on about the hidden fuse. When you say charger unit do you mean the battery charger?

Can a 12 volt problem cause a refrigerator to fail?

A 12-volt problem can cause failure of other appliances and systems if they have 12-volt power to their controls. The refrigerator and air conditioner, even running in propane-fueled mode or on AC power, require DC voltage for their logic circuits, and so may fail to operate when there is a DC system problem.

Why does my camper battery charge when plugged in?

When plugged in shore power at the campsite, most probably, the converter of AC to DC will charge the backup battery bank. All the fans, lamps, water pump, and the rest still function on the 12-volts DC, in just that DC electricity is supplied by the converter rather than the batteries when plugged in.

Why does my coach battery go dead when plugged in?

If you can measure an increase in DC voltage at the battery bank when the coach is plugged in, then the battery charge circuit is at least complete and probably working. If the voltage does not go up when plugged in, look for a blown fuse in the charge circuit in the converter/charger.

What to do if your 12 volt battery is not working?

When your batteries get overworked and overheat, they can lose water through evaporation. The solution is to take the caps off the batteries and add distilled water. But don’t fill the batteries to the top, the water just needs to cover the plates. Be very careful, you don’t want to electrocute yourself.

What does 12 volts mean on a battery charger?

If it reads just over 12 volts, the charger is working (so the issue is your battery). If there’s no reading, the charger needs repairing (so check the fuses). You may sometimes get a small reading of perhaps one or two volts. This is due to electrical resistance and doesn’t mean your charger is producing electricity.

How can I tell if my battery charger is broken?

Test the output voltage from the charger. If the voltmeter has a reading of just over 12 volts, the battery is repaired. If there’s no reading on the voltmeter, the battery charger has a problem with the internal wiring and you need to get it repaired by a specialist or get a new charger (probably cheaper).

How can I tell if my 12 volt battery is charging?

Notice the button on the gray one that you push in to reset. By code this has to be within 18″ of the battery. With the shore cord plugged in take a VDC reading at the battery to see if it is charging. It should be about 13.6 VDC or so. Unplug the power source and then take a reading at the outgoing leads from the fuses for your circuits.

What should the voltage be on a 12 volt battery?

It should be about 13.6 VDC or so. Unplug the power source and then take a reading at the outgoing leads from the fuses for your circuits. If you don’t have any power there then the converter is bad and needs to be replaced. Get back to me and I can make a recommendation.

What should I do if my battery converter is not working?

Unplug the power source and then take a reading at the outgoing leads from the fuses for your circuits. If you don’t have any power there then the converter is bad and needs to be replaced. Get back to me and I can make a recommendation. R.J. Are you referring to the fuse near the battery? The one that is on the wires coming out of the battery?

Why is my auxiliary battery not getting power?

Do you have no power in your coach?

I HAVE NO POWER IN MY COACH ON THE 12 VOLT SYSTEM. NEW BATTERYS HAVE BEEN INSTALLED AND CHARGED UP. IF I USE SHORE POWER

What happens when you take a voltage drop?

Simulate a load that you can keep on steady while you take some voltage drops. If you cannot keep power going to the coil during this time, then you’ll need to create a way to run a couple of brake bulbs or something off the same circuit. Once the circuit is live, you can take some voltage drops. I’ll do my best to explain the procedure.

How many volts to the coil when you take off?

Igntion problem only 4 volts to the coil, when you take off… Hello, my name is XXXXX XXXXX welcome to JA. You have verified that you have 12v potential at the coil by disconnecting the ground, which stops current flow through the circuit.

How to replace a 12 volt coach battery?

I am planning to replace the existing 12 volt house battery with 2 – 6 volt batteries and an inverter/charger. Can I just take the positive and negative cables that attach to the house battery and att … read more we turned the batteries off before turning off the generator. The batteries are charged but there is no power to the unit.

Do you need to know how to troubleshoot electrical problems?

A refrigerator, working appliances, lights, and other machinery run on electricity and when electrical problems arise you need to know how to troubleshoot them. Don’t worry!

What to do if your 12 volt system is not working?

The solution is to take the caps off the batteries and add distilled water. But don’t fill the batteries to the top, the water just needs to cover the plates. Be very careful, you don’t want to electrocute yourself. If tightening the connections doesn’t fix the problem, then you may need to get new cables.

How to troubleshoot a 12 volt water pump?

If the test light only illuminates on one side of the fuse replace the fuse with the proper amperage rated fuse and try the water pump again. If there was 12-volt DC power at both sides of the fuse check for 12-volts at the water pump switch. There should be 12-volts going to the switch, but not out of the switch until it is turned on.

Is there a way to bypass a fuse?

Take the fuse out and hook up a jumper so you bypass it and know that it can’t be in the mix for the problem. Also you can run a jumper lead from the positive of the battery up to the red battery lead on the converter so you bypass the whole lead to see if that is the problem. Sometimes you have to think outside the box to get to the solution.

If you have had the battery out and may have hooked it up backwards this can happen………even for just an instant. If that checks out fine then go the resettable breaker near the battery and see if that has tripped. Go HERE to see what they look like.

Why is my battery charger not working properly?

The second thing you should do after you charge up the batteries is to CHECK EVERY BATTERY CONNECTION. Make sure every battery cable is correctly wired. Then check that all the battery cables are tight against the battery terminals and are not rusted or corroded. Bad connections will cause any battery charger to not function properly.

What happens when a battery is charged but not fully charged?

Fully charged (according to the battery charger) but the voltage is 12.4 or less, the battery is sulfated Sulfation is the natural byproduct when the battery discharges. Naturally, re-charging the battery will reverse the sulfation crystals and turn it back into electrolyte, ready to produce power again.

What happens when a battery is charged at 13.2 volts?

At a charging voltage of 13.2 volts, the converter/charger will maintain a full charge, reduce gassing and water loss. However, this lower voltage does not provide enough gassing to prevent a battery condition called Battery Stratification.

Can You troubleshoot a 12 volt battery charger?

Troubleshooting a 12-volt battery charger is relatively easy. But you’ll need a voltmeter to troubleshoot most chargers. Since the charger is responsible for charging your vehicle’s battery, you want to make sure that it is working, that there is no resistance in the lead wires, and that the voltage coming out of the charger is what it should be.

What’s the best way to troubleshoot an RV electrical problem?

Sometimes the solution is simply the format of your power usage such as what appliances are plugged in, where they are plugged in, and if they are left on. One of the best resolutions is to remember to turn off the appliances when you unplug the RV or shut off the main power.

Can a 110 volt battery be charged by a 12 volt line?

Even if you plan to be connected to 110 volt power, the battery will still supply power to these items and be charged by the 110 volt line through the converter. If your unfamiliar with what the converter does, it will take shore power and convert it to 12 volt power which will safely charge the battery.

Why do you need a 12V to DC converter?

The converter ensures that power is properly distributed throughout the RV, 12V is supplied to the DC systems when the RV is plugged in to shore power or running off generator, and the house batteries are kept charged. It is one of those “out of sight, out of mind” devices.

How does a 12 volt battery light up?

If it senses 12 volts, it lights up. Put the alligator clip attached to the wire onto the negative post of your battery, and touch the positive post with the pointy part. The bulb will light. Excellent!

Also you can run a jumper lead from the positive of the battery up to the red battery lead on the converter so you bypass the whole lead to see if that is the problem. Sometimes you have to think outside the box to get to the solution.

What happens if you don’t have a power converter?

Without a properly working power converter, RV appliances and electrical fixtures won’t run. The converter ensures that power is properly distributed throughout the RV, 12V is supplied to the DC systems when the RV is plugged in to shore power or running off generator, and the house batteries are kept charged.

What happens when an RV battery is plugged in?

Now when your RV is plugged in, the shore power then passes through a converter, which then turns it from AC power to DC power, which is then utilized through the RV’s battery. Leaving Your RV Plugged In, Wrong Or Right?

What should I do if my power converter is not working?

Use a non-contact voltage tester to ensure 110 volts are coursing in the circuit breakers by removing the panel and clamping onto a ground surface. If all is good in the center, you should go to the appliance (s) giving you trouble.
