As far as installing a new PCB, if you have one already, awesome. If you don't and want to save some moolah, follow my post in aboit 10 days. I'll do parts and tools used, where to get parts etc. Otherwise it's just unscrew the connector at the bottom, unbolt it from the firewall and put the...

You are absolutely correct. It turns out my battery solenoid was stuck, then my start solenoid went out. I bought the solenoids at O'Reilly before I came offshore for $32.00 each and will post a rebuild PCB thread when I get back in covering removal, disassembly, rebuild and reinstallation.

OK, after more digging, I found the following illustration: Based on this, all of my gauges are connected through the switch to the battery. Logically, my switch has failed in the "closed" position, resulting in the above mentioned problems. I found one from Eastern Surplus and WI order it...

So again, my question is this I guess.... Is the PCB in line *before* the switch? As in it gets power regardless or is power sent to the PCB through the switch? As I said, my guages etc all stay on. Shouldn't the switch kill that?

The question I have, though, is shouldn't the battery switch kill power to the PCB? From what I'm seeing, the switch is "upstream" from the PCB. Turning the switch off should kill electricity to the entire circuit and that isn't happening, so unless I'm reading power flow incorrectly, my first...

All- One of the issues I have with my 5 ton is the battery switch will not kill electrics to the starter or dash gauges. In the off position, it is possible to still start the truck and my gauges will eventually drain my batteries. To "fix" this and add additional security to the truck, I've...
