mchero, I dont know enough about the charging relay yet to know how it works, I was under the impression that if the starter battery was DEAD the relay would instantly throw the house battery into play to start the vehicle and blow my 150 amp fuses.
But if the relay only lets me manually direct house battery amps to the starter batt then I am good to go, just let the house battery charge the start batt for 15 minutes , then turn the relay off and try and start.
I am trying to understand how the relay works, but the website doesnt go into enough detail for a 12v newbie.
