Control panel needle doesn’t zero

[Robert1351]

What does it mean when the needle indicating cab or leisure battery doesn’t zero? This has been an intermittent issue. I’ve just fired a new cab battery and the needle sits at 12v. The c battery shows 12.5v at the cigarette socket but not charging with hook up. It shows the leisure battery charging on hookup. Seems odd.

This doesn't completely answer but often you used to have to select which battery you were using and therefore where the EHU charger sends power.

Thanks but I have no selector switch. I think the Electrobloc charges both at once or possibly in sequence. My belief lies mainly with a 2 amp floating charge to the cab battery all the time but I suppose if the L battery is low then it might not do that and just focus on one? I’m going to isolate the L battery and see if that makes any difference ……..

Nope. I think I may have to phone a friend. Unfortunately he’s very busy.

Leaving the van hooked up for a few days seems to be gradually resolving the issue. Thanks for your input.
