Has the Charging System Check been performed?

--

Go to Step 2

Go to Charging System Check

Inspect the ALT/START fuse in the engine wiring harness junction block (underhood fuse relay center).

Is the ALT/START fuse open?

--

Go to Step 3

Go to Step 4

1. Locate and repair the source of the overload in CKT 739 (PNK).
2. Repair the wiring harness if a short circuit was found. Refer to Wiring Repairs in Wiring Systems.
3. Replace the ALT/START fuse.

Is the repair complete?

1. Connect a J 39200 DMM from the positive (+) battery terminal to the negative (-) battery terminal.
2. Measure the voltage.
3. Turn the ignition switch to the RUN position.
4. Connect the J 39200 DMM from the ALT/START fuse, cavity L 8 to ground.
5. Measure the voltage.
6. Turn the ignition switch to the OFF position.

Was the voltage at the ALT/START fuse equal to the battery voltage?

--

Go to Step 6

Go to Step 5

Repair the power supply circuit to the ALT/START fuse.

1. Disconnect the generator connector.
2. Connect a J 39200 DMM from the generator connector, cavity S to ground. Refer to Using Connector Test Adapters in Wiring Systems.
3. Measure the voltage.

Is the voltage equal to the specified value?

B+

Go to Step 8

Go to Step 7

Locate and repair the open or high-resistance connection in CKT 2 (RED) between the starter solenoid B terminal and the generator S terminal.

Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

1. Connect a J 39200 DMM from the generator output terminal to ground. (The output terminal wire is connected to the generator with a ring terminal and nut.)
2. Measure the voltage.

Is the voltage equal to the specified value?

B+

Go to Step 10

Go to Step 9

Locate and repair the open or high resistance connection in CKT 2 (RED) between the starter solenoid B terminal and the generator output terminal.

Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.
