With the DRBIII , read DTC's.
Are there any Charging System trouble codes?
Yes → Refer to Symptom list for problems related to Charging.
No
5 Turn ignition on, engine not running.
Measure voltage between the Generator B(+) Terminal and the Battery (+) Post.
Caution: Ensure all wires are clear of the engine's moving parts.
Start the engine.
Is the voltage above 0.4 volt?
Yes → Repair the B(+) Circuit for high resistance between the Generator
No
6 Start the engine.
Warm the engine to operating temperature.
Caution: Ensure all wires are clear of the engine's moving parts.
Measure voltage between the Generator case and Battery (-) Post.
Is the voltage above 0.1 volt?
Yes → Repair Generator Ground for high resistance, Generator Case to
No
7 Ignition on, engine not running.
With the DRBIII , read the Battery voltage and record the results.
Measure Battery voltage B(+) to B(-) Terminal and record the results.
Compare the two voltage readings.
Is the voltage difference less than one volt?
Yes → Test Complete.
No
8 Ignition on, engine not running.
With the DRBIII , read the Battery voltage and record the results.
Turn the Ignition off.
Disconnect the PCM harness connector(s).
Note: Check connectors - Clean/repair as necessary.
