Why is my coach battery not fully charging?

A drop in the house battery bank voltage from 13.3 to 12.1 in just a couple of minutes indicates either a MASSIVE draw or much more likely one or more bad batteries. So, I would start by fully charging them and have them load tested. A bad battery can give all kinds of weird symptoms.

What kind of battery does a coach use?

Both should be 14-14.2 VDC with engine running. On many coaches, the charger or converter (120 VAC to 12 VDC) only charges the house battery bank, not the chassis bank. Which bank is not being charged?

Is the coach battery charged by the alternator?

Rich. The Inverter is a PowerSource PC50 producing up to 50A at 12VDC. The alternator is charging the chassis battery just fine, and I’ve verified the output of the alternator. But I don’t think the coach batteries are charged by the alternator… is that correct?

Where do I Disconnect the coach battery in a RV?

The RV uses an Intellitec battery disconnect system. Inside the door are two switches to disconnect the chassis and coach batteries (see photo below). Also below photos of the Intellic disconnect relays inside the power distribution box that’s in the engine compartment.

What kind of battery charger does coach RV use?

I have checked the 120VAC to 12VDC inverter that I assume is supposed to charge the coach batteries. It produces 13.5 VDC (with no load) and powers all of the 12V components in the RV. The RV uses an Intellitec battery disconnect system. Inside the door are two switches to disconnect the chassis and coach batteries (see photo below).

Where does the power from the coach batteries come from?

Power from the batteries enters through the two copper bars in the center (see red arrows pointing up). The cables labled S and I are from the rocker switches inside the RV that activate the disconnect relays. When activated, the relays connect coach and chassis power to the RV.

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.

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.

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

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 the battery on my RV not charging?

If you check the batteries with a multimeter or voltage meter an hour later, they should still give you the same fully charged reading. If the voltage numbers are going down, then it’s likely a battery problem. Most of the time you will need to replace the problematic battery.

What should I do if my car battery does not charge?

You can do one of two tests to confirm that your battery maintains the charge: the hydrometer or battery load tests. If your battery did not pass any of these tests, you might need to replace your vehicle’s battery. One of the fastest ways to confirm it’s not your battery causing the issue is using a jump start.

Can You charge an RV battery while driving?

No RV Battery Charging While Driving. The house batteries and the engine battery should receive a charge via the alternator on the engine while actually driving. It is plausible to run the generator while driving, but if the alternator is sized properly, both battery systems can be effectively charged while driving.

Why is my coach battery not charging from the engine?

When I check the battery at the charger it shows the same voltage as the battery. When I do this same test while plugged in or running the generator the voltage is higher indicating it is charging. I have a used 1999 Winnebago Chalet. I installed a new progressive power dynamics replacement charger before I left.

What should the battery voltage be in a coach?

Start the coach and run it at around 1500 Rpm’s and the battery voltage should rise over 14 volts and then should drop down as Rpm’s are decreased, inspect the alternator belt make sure it is snug and not slipping.

Can a car battery be charged while driving?

It is powered by 120-volt AC electricity and should charge while plugged into shoreline power or when running the generator. The house batteries and the engine battery should receive a charge via the alternator on the engine while actually driving.

Why does my RV battery not hold juice?

We received a question from an RV Repair Club member asking why their RV battery wasn’t holding any juice after a full charging cycle. While the problem of an RV battery not charging typically stems back to one common issue, there are a handful of other possibilities.

Why is the battery on my ALINEr not charging?

There will be a slight draw on the batteries from the radio presets and engine CPU for the engine battery, and a draw from the LP leak detector so it’s good to isolate those. My battery on my aliner is not charging after I drive with it all connected to my destination. The battery itself was tested and is chargeable.

Why does my Jayco trailer have no power?

The two most common reasons for this are that the battery is hooked up wrong and the leads are reversed and that will blow the reverse polarity fuses in the converter OR you have a bad or tripped shortstop breaker down under the front there that by code has to be within 18″ of the battery(s).

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.

Can a house battery charge a RV battery?

Definitely yes, it charges. Every time your RV is plugged in, your house battery gets charged. Whereas it is just a trickle charge, it may deplete the electrolyte levels of your battery cells.

What do I need to clean my coach battery?

However, the battery cables for both the chassis and coach batteries must be cleaned. A good steel wire brush and top post battery cleaner are really all that’s needed. Turn off all your battery Main Switches, disconnect from shore power, have your generator off and go to it.

Can a coach battery power a washer and dryer?

The coach batteries will not be able to power your Roof AC units or Washer/Dryer – those are high amperage draw appliances that would literally suck all the energy from those batteries too quickly!

What should I do if my RV battery is not charging?

Most of the time you will need to replace the problematic battery. You will need to replace the batteries with a new one or reconditioned 12-Volt RV batteries. Though if you have the time on your hands, you might be able to find a battery technician who can recondition your batteries for a minimal charge.

What are the battery levels on a coach RV?

The batteries not running are all 12.58 The Chassis battery running is 14.35 The Coach batteries running stay at 12.58 Plugged in not running the Batteries are at 12.58 I checked all fuses and breakers and everything is ok not tripped or blown.
