Express 1/2 Ton Van V8-5.7L VIN R (1999)
Starter Motor: Testing and Inspection
Starter No Load Test (PG260)
TOOLS REQUIRED:
-
J 39200 Digital Multimeter
-
J 35590 Adapters, or equivalent
NOTE: Never operate the starter motor more than 15 seconds at a time without pausing in order to allow it to cool for at least 2 minutes. Overheating
will damage the starter motor.
IMPORTANT: Verify that both batteries are in good condition.
1. Disable the fuel system by removing the fuel solenoid fuse.
2. Calculate the current draw. Select the 200 A or 2000 A scale on the current clamp.
3. Zero the current clamp. Clamp the J 39200 to the negative battery cable.
4. Crank the engine. Observe the meter readings. The reading should be 330 - 360 amps. If the amperage is over 360 amps, an internal starter failure
may be the cause. If the amperage is under 330 amps, a battery cable or connection may be the cause.
