Fuel Gauge Test: Van
- To check power source, turn ignition switch to "ON" position. Check voltage between terminal No. 11 and ground. If there is 12 volts, go to step 3).
- If there is not 12 volts, check for blown fusible link or fuse. Check harness continuity between battery terminal and combination meter. Check for malfunctioning ignition relay and/or ignition switch.
- To check voltage output, measure voltage between terminal "F1" and ground. See Fig 1
. If there is not about 8 volts, replace voltage regulator. If there is 8 volts, connect a jumper wire between terminal "F2" and ground for less than 10 seconds.
- Fuel gauge should move smoothly from "EMPTY" to "FULL". If it does not, replace fuel gauge. If it does, perform FUEL TANK SENDING UNIT TEST
. If sending unit is okay, repair or replace harness between combination meter and fuel gauge unit harness.
