DEFINITION: The volts gauge in the instrument cluster is accurate, and it correctly indicates a high or low Voltage condition.

1. Turn off all vehicle electrical loads.
2. Start the engine and let it idle briefly.
3. Use a J 39200 DMM to measure the voltage from the battery positive (+) terminal to the battery negative (-) terminal.
4. Compare the J 39200 DMM voltage with a simultaneous reading of the volt gauge in the instrument cluster.

Is the difference in voltage less than the specified value?

1 V

Go to Step 2

Go to Volt Gage Inaccurate or Inoperative in Body and Accessories.

Perform the charging system check and make any repairs indicated by the charging system check. Refer to Charging System Check

Is the charging system OK?

--

Go to Step 3

--

While the engine is operating, does the volts gauge indicate a higher than normal voltage?

--

Go to Step 4

Go to Step 5

Repair the high resistance connection in CKT 2 (RED) between the generator S terminal (D terminal on CS-130 generator) and the starter solenoid B terminal.

Is the repair complete?

--

System OK

--

1. Turn the ignition switch to the RUN position (engine not running).
2. Measure the voltage at the GAUGES fuse in the instrument panel (IP) fuse block.

Is the voltage near the specified value?

B+

Go to Step 7

Go to Step 6

Repair the high resistance or intermittent open circuit on the power side of fthe GAUGES fuse.

Is the voltage at the GAUGES fuse near the specified value?

B+

System OK

--

Repair the high resistance or intermittent open circuit between the GAUGES fuse and terminal I of the generator connector (terminal C of CS-130 generator) .

Is the repair complete?

--

System OK
