Trombetta relay Questions
Hello team, My house batteries were not ending the driving day charged to the 12.8v ideal level. I replaced the original Trombetta 114-1211.010 with the same item but the model # ended in 030. I was...

Assuming the Trombetta is working properly, you need a complete circuit to charge through the Trombetta. Power needs to come through from the charging battery to the Trombetta, so connect up a battery charging cable from the charging battery negative to near the Trombetta, then measure the positive and negative at the trombetta. Should be the same as at the charging battery.
Then using the same negative jumper cable, measure from the positive house battery to the negative from the charging battery. I am thinking you might find good voltage there. If you do find good voltage there, then connect that negative from the charging battery to the negative on the house battery, and see what the voltage across the house battery is now. If you find that is is the same as the charging battery, you have just proved that the negative terminal on one of the batteries is not connected to the negative terminal on the other.
Many many times people think power is not getting there, but it is, just not getting back. Hope this helps.
