Hi there. First post and I’m sorry it’s a question.
I have just fitted the DC to DC smart charger and I’m receiving major input voltage fluctuations which I believe isnot allowing the unit to detect the engine start. I have put a multimeter across the terminals and see a steady 12.8 v engine off and 13.8 volts when running. I’ve doubled checked the cables etc and they look great. I swapped in this unit after removing a split charger so I know that all worked.
many help would be greatly approached.
