I'm just getting to grips with my LH113 Hiace Camper and I've found a fuse that keeps blowing. This fuse is a 25A fuse that is between the vehicle battery and the leisure battery when the engine is running. I have checked out the circuits and all appears normal. When the engine starts the Riemo relay operates and maks the connection to the leisure battery. The fuse seems to blow when this happens. When the engine is running and the fuse out the voltage between the two batteries is 1.36V. Anyone got any ideas? Perhaps I need a slow-blow fuse to cover the initial surge?
