Put a new ground to to the block and since have taken it out
I insured the battery was fully charged and had running for 2 hrs stop and started it upto 6 times regularly checking voltage with meter after the 2 hrs checked it and was reading 12.15v from 12.60v from when initially charged
Still staying 12v low , can u run these for 2 hrs and stop and start and only drop 0.40v or can I say that the rectifier is charging but only trickle charging
