Vehicle battery .

[Philip Reynolds]

My vehicle battery discharges when I am hooked up to 240 volts,and using the facilities on board. I have no problem when not hooked,came back from a week abroad and she started first time. I have a Lunar Road star 720 2004. Many thanks,Phil

Fuse or onboard charger may be problem,have you put a volt meter on charger to test output,and is it a old type,if so change it to a smart charger,more info required on age of van and type of charge unit etc.
