So, I had a great idea. I have 2 batteries connected via a solenoid which I can connect/disconnect at will via a in-cab switch. I wanted to add a battery disconnect to the primary battery so I can take it out of the loop when/if I need to. I saw TR's other post w/ the battery disconnect on the ground (Vs Positive) and when I picked up a dial battery disconnect, it only fits the ground (makes sense).
However, my solenoid connects the positives of the two batteries, not the grounds. The Grounds are connected together permanently. I was wondering, If I disable the ground to the primary, though the secondary ground is still active, and the primary positive is still active will that Mess up the batteries? Will a current go from the Positive of one battery to the negative of another? I assume so.
Here is a pic of the solenoid setup:
Here is my (Very quick diagram, yes it is the worst I have seen on this board, but I could not find my Visio CD)
Pri. Battery = Primary, on all the time, the one I want to disable via the manual disconnect, itís Positive is permanent.
Sec Battery= secondary, itís Ground is permanent, itís positive is switched.
The Yellow thing represents where I want to put the manual disconnect.
Is there a better way? Should I set a manual disconnect to the Positive side of the primary?
I know this is pretty confusing, but I have faith in the electrical gurus to set me straight.
