Voltmeter Wiring Changes (to replace the ammeter)

Up to Chassis 334

• Cut back and tape off the heavy white wire at the passenger's side of fuse 1.
• On the circuit breaker, remove the harness brown wire (not the jumper from the solenoid).  Tape it off or cut it back into the harness.
• Run a new wire (10 gauge minimum) from the circuit breaker (or on very early cars without a circuit breaker, the battery side of the starter solenoid) to the terminal where the white wire was connected.
• Run an additional heavy wire (6-8 gauge) wire from the alternator "Bat" terminal to the hot (battery) side of the starter solenoid or directly to the battery.
• Run an additional wire (20 gauge minimum) from the fuel gage terminal with the green wire to the + (signal) terminal of the new voltmeter.
• Tape off (seperately) the old ammeter wire connections.
