JEEP CJ7 GAUGE WIRING

Jeep CJ Gauge & Sender Diagnostics - 4x4Wire
Jeep CJ Gauge & Sender Diagnostics. Short Cuts: By: John Foutz - 3/2000 DO NOT hold it for very long in this position, just touch and release the wire. If the gauge does not move from EMPTY either the wiring has an open circuit (no voltage, or no connection to ground) or he gauge is bad. If it does move, the sending unit is bad.
