    We had some work done on our mh last Autumn and ever since, we've experienced issues not had previously.

    Our current issue is that the leisure battery does not appear to charge effectively when we are moving. The battery is 2 years old. The mh control panel lights up with all 4 battery indicator lights when the engine is running but when the engine stops, only the first 3 lights illuminate. The battery then appears to run down faster than prior to the work. I'm not convinced that it charges when we're moving. Is there a common cause of batteries not charging when the engine is running?

    I don't have a multimeter with me but have spare fuses.

    MAKE, MODEL AND YEAR!

    We are not mind readers!

    Sounds like you think you have a leakage to earth wasting power but not bad enough to blow a fuse. Standard check is to disconnect your positive cable from the hab battery and put a multi-meter between the two and then test each circuit with the fuse removed from the circuit, not the battery and the circuit showing current is the one with a leak.

    You really need a multi-meter to be able to check the lines of each cable run when you pull the fuses.

    Other than this you need to go to an auto electrician/dealer to resolve this issue
