150amp fuse on the main line feeding the fuse bus in the console blew, put another one in and it blew instantly. I have the ground from this bus going back directly to the battery.
I then removed the main power and ground wires to the bus assuming the positive had grounded itself. Even though I had a grommet on the fire wall, I figured it may have worn through over time and cut the wire.
After ripping it all out, there were no cuts in either line and when I reinstalled, power went to the console. The strange thing is that I never found the issue...but it started working again; sorta.
When I put power to the 2nd battery gauge and trans gauge (both AutoMeter), the readings were way off. When I apply power to the trans gauge, the dial now goes backward until it hits the mechanical stop. On the second battery, it stays at 12.7 volts (on the AutoMeter gauge) even with the truck running and the batteries in parallel....however the main battery still indicates 14+ volts.
I have no blown fuses on the bus and when i checked the wiring, it seems to be ok to each individual component.
My next step is to take out a meter and see what's going on with my two batteries and the big 500amp relay I have between them. From there, I'm going to apply the meter to each circuit on the bus, gauges and everything else plugged into it.
What's strange is that I also have CB running through the bus and it's working without issue.
Thoughts?
