DIAGNOSTIC TESTS
Short to Ground:
4.Set the VOM to measure resistance. Connect the positive (+) test lead to the case housing of the BCR. Connect the negative

RESULTS:
1.If any of the previous steps has failed, replace the Battery Charge Rectifier.
2.If the BCR tests good, refer back to the flow chart.
TEST 20 - CHECK 10 AMP CIRCUIT BREAKER
PROCEDURE:
1.Set a voltmeter to measure resistance.
2.Locate the 10 Amp circuit breaker (CB1) in the control panel. See Page 17 for Circuit breaker location.
3.Disconnect Wire 15A and Wire 13A from the circuit breaker.
4.Connect one meter test lead to one terminal of the circuit breaker. Connect the other meter test lead to the remaining terminal on the circuit breaker. Continuity should be measured. See Figure
RESULTS:
1.If continuity was measured the breaker is good refer back to the flow chart.
2.If INFINITY or a open condition was measured replace the circuit breaker.

Test 21- Check 10 Amp Fuse
Figure 6-27. – 10 Amp Fuse (Located in Rear of
Control Panel)
PROCEDURE:
Push in on fuse holder cap and turn counterclockwise. Then, remove the cap with fuse. Inspect the Fuse.
RESULTS:
If the Fuse element has melted open, replace the Fuse with an identical size fuse. If Fuse is good, refer back to flow chart.
Test 22- Check Battery & Cables
PROCEDURE:
1.Inspect the battery cables and battery posts or terminals for corrosion or tightness. Measure the voltage at the terminal of the Starter Contactor and verify
