Electric Choke/Ammeter wiring
Hey Folks!
For my 76 F250 Ranger, I've seen several diagrams for alternator wiring with idiot light, but my baby has an amp gauge that is not connected, as well as the electric choke, and I need to know where to hook these up...the previous owner had stuck in a sunpro gauge cluster instead of just replacing the dash cluster voltage regulator, but the amp meter was never hooked up, and I can't figure out where to hook the original cluster wires. Can anyone help????
Thanx!!

Somewhere in the harness out at the starter solenoid you should have a splice in the black/orange wire that goes from the starter solenoid to the alt output. This splice is called a "shunt". It is just a very low value resistance. On either side of the shunt you should have two smaller wires spliced in. I am looking at a later diagram, but yours is probably the same. These two small wires are red/orange and yellow/lightgreen. These two wires go to the factory amp guage.
The factory amp guage is really a very sensitive voltmeter. It is reading the very small voltage drop across the shunt, giving you a reading. If they had the aftermarket amp guage hooked up, don't try to hook the factory one up the same way or you will ruin it.
