Test Description

The number below refers to the step number on the diagnostic table.

If the test has shown the generator to be OK, however the condition remains, test the PCM or its control circuit(s) to the generator.

Step	Action	Value(s)	Yes	No
SCHEMATIC REFERENCE: Starting and Charging Schematics
1	Did you perform the Diagnostic System Check - Starting and Charging?	--	Go to Step 2	Go to Diagnostic System Check - Engine Electrical
2	Start the engine, observe the charge indicator on the instrument cluster (IPC) . Is the charge indicator ON?	--	Go to Step 3	Go to Symptoms
3	Important: The green POWER lamp of the tester should remain illuminated while the tester is being used. Turn OFF the ignition. Connect the red lead of the J 41450-B Generator Electronic Tester to the generator output terminal. Connect the black lead of the J 41450-B Generator Electronic Tester to the metal generator housing. Does the green POWER lamp on the tester illuminate?	--	Go to Step 6	Go to Step 4
4	Measure the voltage from the output terminal of the generator to the generator metal housing. Does the voltage measure equal to the specified value?	B +	Go to Step 14	Go to Step 5
5	Measure the voltage from the output terminal of the generator to the battery negative terminal. Does the voltage measure equal to the specified value?	B +	Go to Step 12	Go to Step 11
6	Caution: Make sure that the load is completely turned off before connecting or disconnecting a carbon pile load tester to the battery. Otherwise, sparking could ignite battery gasses which are extremely flammable and may explode violently. Connect a carbon pile tester to the vehicle Important: Ensure that all generator output circuit wires pass through the inductive probe. Connect an inductive ammeter to the output circuit of the generator. Disconnect the generator harness connector. Locate the matching harness connector on the J 41450-B , and connect the connector to the generator. Does the red DIAGNOSTIC lamp on the tester illuminate?	--	Go to Step 7	Go to Step 13
7	Start the engine and allow it to idle for 30 seconds. Increase the engine speed to 2500 RPM. Does the red DIAGNOSTIC lamp on the tester illuminate?	--	Go to Step 15	Go to Step 8
8	Maintain the engine speed at 2500 RPM. Important: If the generator is not capable of producing the Load Test amps, operate the generator at it's maximum possible output. Turn ON the load of the carbon pile tester and increase the load until the generator output is equal to the Load Test value given in Generator Usage . Does the red DIAGNOSTIC lamp on the tester light?	--	Go to Step 15	Go to Step 9
9	Maintain the engine speed at 2500 RPM and continue to operate the generator at the load test value. Measure the voltage drop from the output terminal of the generator to the positive terminal on the battery. Refer to Circuit Testing and Connector Repairs in Wiring Systems. Does the voltage measure greater than the specified value?	0.5 V	Go to Step 11	Go to Step 10
10	Maintain the engine speed at 2500 RPM and continue to operate the generator at the load test value. Measure the voltage from the output terminal of the generator to the positive terminal on the remote battery stud located in the underhood accessory wiring junction block. Does the voltage measure greater than the specified value?	0.5 V	Go to Step 12	Go to Step 16
11	Repair the high resistance or an open in the output circuit of the generator. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair?	0.5 V	Go to Step 16	--
12	Repair the high resistance or open in the ground circuit of the generator. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair?	--	Go to Step 16	--
13	Disconnect the J 41450-B tester harness connector from the generator, but leave the alligator clips connected so that the green POWER lamp remains illuminated. Connect a jumper lead, with an in-line 100-ohm resistor between the J 41450-B tester harness connector terminal B [terminal L for CS-130D generators] and a good ground. Refer to Engine Electrical Connector End Views . Does the red DIAGNOSTIC lamp illuminate?	--	Go to Step 15	Go to Step 14
14	There is a problem with the J 41450-B . Refer to the manufacturers instructions, how to test the J 41450-B for proper operation. Has the J 41450-B tester been replaced?	--	Go to Step 3	--
15	Replace the generator. Refer to Generator Replacement Is the repair complete?	--	Go to Step 16	--
16	Operate the system for which the symptom occurred. Did you correct the condition?	--	System OK	Go to Step 2
