Fuel Gauge
- Disconnect fuel gauge sending unit wire. On Colt and Champ models, connect a 17 ohm resistor between wire and ground. On all other models, ground sending unit wire. Fuel gauge should read full.CAUTION: Keeping the wire grounded too long can damage coils in gauge. Perform test as quickly as possible.
- On Colt and Champ models, connect a 120 ohm resistor between sending wire and ground. On all other models, connect a 95 ohm resistor between sending wire and ground. Gauge should read empty.
