Dual Batt wiring - have isolator need help
So I purchased the isolator from the automotive shop. Looks like the ford relay allready on my fenderwall however this is the 100% duty isolator. There are 4 posts, two big-uns for the positive connections on both batterys. Two 16ga, posts, one is labled ground, (simple enough) and one is labled "accessory post on ignition switch".
I dont understand what that means, "accessory post on ignition switch."
Someones done this before im sure, probably with the same isolator. Some diagrams I have looked at point to the starter, others just say fuse box.
Help!

Sheeeeeeeit... Doesnt help directly but shone a light for me. Guess what I really need to know is where do I connect (what fuse to tap) for the ignition "on" post on the isolator.
I have no book for the truck, I know, tsk,tsk.

Maybe if I knew what truck you have I could tell you where to connect it.
If your truck is the 1990 that is in your information then it would be the Black wire with a light green stripe that is going to fuse #6, 11, 14 & 17 in the below diagram. You could use the output of one of those fuses also.

After reading the FusePanel diagram it says under PowerDistribution that fuse 16 is powered all the time. I dont know if I am supposed to use that fuse because I think I am looking for a power source that is live after the ignition switch is in the on position. Does that make sence? I assume the ignition accessory terminal on the battery isolator is to control it.

Yes you are looking for a power source that only has power in the ON or ACC position. The ignition accessory terminal on the battery isolator is to control the unit off and on. On will let you charge both batteries and off keeps you from draining the engine battery.
