littlebill, thanks for chiming in, I just learned ALOT about my charging relay in your post. And hope you can teach me some more.
"realistically you should never have a dead starter battery, that said if you do, i would recommend waiting a minute or so in override before attempting the start"
But how would I know I had a dead starter battery before I turned the key on and tried to start the engine.
Does the relay automatically/instantly send power from the house battery to the start battery if needed, or does it require a manual switching?
"in this case using the override switch will allow the relay to connect the banks and start the motor".
What position would I turn the over ride switch too? Does that "override" switching include pushing the button "down"?
In using the over ride switch, would I just let the batteries coexist for 15 minutes or so, then turn the switch off so to disconnect the two batteries before starting so I dont blow my 150 amp fuses? OR try and start the vehicle while they are both bonded together?
thanks
its pretty straight forward your manual is below
Clicky
long story short if the voltage is above 13v, either from the alternator or solar or generator or shore power they are connected.
in your first question of dead starter you have to ask yourself a couple questions, is the solar working are you on shore power? are you above 13v,if so the starter battery is connected to the solar/ shore power,
if your not doing solar/shore power etc and the voltage is below 13v, then the banks are not connected, thus it would just be the starter battery trying to start the engine.
even if the voltage was over 13v at the time you tried to start, the second you tried to start the voltage would easily drop under the 13v and disconnect the house battery, fuses can take a bit to blow depending on if they are slow blow etc.
i don't personally own this relay, but looking at the red switch that comes with it, "on" connects the battery's for as long as its in on position regardless of voltage, off is a permanent disconnect regardless of voltage, and auto works off voltage per side, (according to the manual after selecting off or on, auto takes 10 minutes to renable itself)
hope that helps
