TEST
1 NOTE: Verify that the Battery is able to pass a load test before continuing.
Ignition on, engine not running.
With the DRBIII , read the Battery voltage and record the results.
Measure Battery voltage between the Battery Positive and Negative Terminals and
record the results.
Compare the two voltage readings.
Is the voltage difference less than one volt?
Yes → Go To 2
→ Go To 8
No
2 Ignition on, engine not running.
Measure the 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.

Yes → Repair the excessive resistance in the Battery Positive circuit
→ Go To 3
No
3 Ignition on, engine not running.
Record all DTCs and freeze frame data, now erase Codes.
Carefully inspect all connectors for corrosion or spread terminals before continuing.
With the DRBIII actuate the Generator Field Driver.
