The other 74AH i use as the leisure battery gave a reading of 12.5v with ignition off.
Engine running 54 AH starter reading 13.8v and 74AH leisure reading 13.5v
Should i not be getting the same readings from both batteries when the alternator is charging
As I know yours is an early Westy setup Paul, the split charge 'link' between the two batteries is relatively short so the 0.3volt difference is a little bit much TBH....the split charge wiring on these isn't the heaviest and I suspect the puny relay may well have some burnt contacts creating that drop. (relay is to the side of the leisure, drivers side)
