Does running RV engine charge house batteries?
Your house batteries do indeed charge when plugged into shore power. If your rig’s chassis battery (or batteries, in larger motorhomes) aren’t charged by shore power, which is more common in smaller rigs, they’ll only be charged by the alternator when the engine is running.
Will my car battery recharge from running the engine?
The good news is that yes your car battery will charge when idling. Your alternator produces electricity when your car’s engine is running so as long as your car engine is on and your alternator is working properly your car battery will be charged.
Can you charge a battery while it is running?
In the simple case described by others here, no, it isn’t possible to charge and discharge a battery at the same time. It is possible in some instances to discharge the battery of a device even while the device’s charger is connected and providing current, but the battery itself is only discharging.
Can a coach battery be charged while 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. Once you stop for the night, plug the coach into 120-volt AC park power and then the Parallax can top off the house batteries. (The Parallax will not charge the chassis battery).
Do you have to Rev the engine to charge the battery?
Yes, revving your engine will charge your battery, but not all the time. Generally, the car system ensures the battery is charged at all times. However, significantly discharged batteries will require you to rev the engine to provide some charge. Commonly used lead-acid batteries will usually be charged when the alternator is running.
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.
How does an alternator charge an RV battery?
While the engine is running, the alternator continuously charges the starting battery. Second, the RV’s house/service battery or battery bank (typically deep cycle batteries) run everything electrical in your living space when you aren’t plugged into shore power.
Why are my coach batteries not being charged?
IF you have good voltage from the alternator something downstream is not allowing the batteries to charge, follow all the wires off the alternator. Most RV’S have a battery isolator or solenoid that will allow the coach and house batteries to charge while driving.

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.
