Ammeter to Voltmeter...who does it?
It was actually a Mopar part, added to the chassis cab at the Warren Truck Plant. Some chassis cabs got it, some didn't. I don't remember the option code off the top of my head, but it was definitely a Mopar option. Since I plan on doing the MAD bypass, would it matter where in the wiring I put that 20A circuit breaker? Firewall in the engine compartment does seem like a better place.
You just jogged my memory.
My junction blocks. The ammeter is definitely on the charging circuit. The fusible link is NOS...my old one was crunchy but not yet burned out.

The 10ga. positive wire with the inline fuse goes to the coach/house battery charging solenoid. Maybe this is causing the ammeter to read +25, because the coach/house battery is on its last legs. The chassis van battery is brand new.

The coach/house battery charging solenoid. The middle post is the 12v switched power to energize the solenoid; 10ga. red wire on the right is the one from the chassis van battery; grey wire on the left is to the coach/house battery. Yellow wire is what I used to go to my electric fuel pump, which is by the fuel tank...there are no switched 12V sources back there.

My plan, once I do the ammeter bypass, is to run a 10ga. wire from the alternator directly to the coach/house battery charging solenoid, instead of having it run from the chassis cab battery, that way the chassis cab battery isn't having to be the conduit to charge the coach/house battery.
