Re: How to wire a continous duty solenoid?
Mine is set up so that when the ignition is turned on the solinoid pulls in. This allows the charging circuit to charge the battery. The winch, fan, and a couple of other things run off this second battery only. There is no connection save the charging wire. I figured that if I ever need the second battery to start the jeep, I can use jumper cables between them.
So, put one side to the Alternator, one side to the battery (those are the big ones) and just take a wire from a hot and see which of the two small post pulls in the solinoid. Tie thjat one to the wire that is hot from the ACC. I also ran my wire thru the oil press switch so that it would not be connected unless the engine was running.
I have ran this setup for years on all my tow rigs and any thing else that has two batteries.
Every mod cost cash twice.
once for the mod and once for what you find out
you want to do next.
