Temperature Gauge
- Unplug sending unit wire. Connect VW tester 1301 between wire and ground. Turn ignition on. With tester set at 500, gauge should indicate cool. With tester at 60, gauge should indicate hot.NOTE: Tester settings do not indicate resistance in ohms. Resistance values were not available.
- If gauge needle does not move at all, check continuity between sender wire and gauge. If needle moves but does not match specifications, replace gauge. If gauge works correctly with tester but not sending unit, replace sending unit.
