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 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.
Why are the batteries on my coach going dead?
The engine alternator was simply providing the DC voltage while the engine was running. Regardless of the brand of motorhome, the brand and type of converter/charger installed and whether or not any disconnect devices are employed, it’s obvious the batteries are not receiving a charge while the coach is plugged in to shore power.
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 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.
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).
Why does my RV battery not charge properly?
As Dave mentions, there could be a few different causes if you discover a battery not charging properly on your RV. Most often, though, battery capacity depends on the type of charging cycle you conduct prior to operation.

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.
Why does my coach battery keep going dead?
Brett, if this member is having both the house and the coach batteries going dead, it seems there has to be some sort of drag on them and his inverter is not keeping up or not working. If there is something dragging down both batteries down he might also have a bad isolator. The only thing on should be the radio/clock.

What is the solenoid on a coach battery?
Yesterday I was able to look at the Solenoid (I believe it is a solenoid and not an Isolator) in the battery compartment. It seems there was another “Solenoid” daisy chained to this one and the positive cable that connects to the battery was in the middle.
