CONDITION:
When attempting to start the vehicle, the customer may hear a click, but the starter will not crank. This condition is usually intermittent.
CAUSE:
1.
The connections to the starter, battery, or ground may be loose or corroded. The battery may also have insufficient charge.
2.
The starter motor may have insufficient internal lubrication and/or too high drive spring force.
3.
The installation of an aftermarket theft alarm system (including the "Goodwrench" system) may add enough additional resistance to the starter
solenoid circuit to prevent the starter from engaging. The wiring in the alarm system package may not be able to carry the total current of the
starter solenoid circuit under all conditions.
CORRECTION:
1.
If the vehicle has the "Goodwrench" alarm system installed, rewire the alarm module circuit with 10 gauge wire. The instructions are in the
"ALARM SYSTEM REWORK" procedure below. If another brand of alarm has been installed, a similar rework may have to be done to insure
that the wiring from the ignition switch to the park/neutral switch is at least 10 gauge.
When the rewire step is complete, continue with Step 2.
2.
Check both the positive and negative connections at the battery, the battery ground to the engine block, and the connections to the starter motor.
Check the battery to insure that it is properly charged.
3.
Using a digital multimeter, check the voltage at the starter solenoid "S" terminal while attempting to start. This test MUST be done while the
vehicle is experiencing a "Click, No Crank", not during a good start.
If the voltage is LESS than 9.0 volts, check for high resistance in the wiring, connections, ignition switch, or park/neutral switch. If the voltage is
GREATER than 9.0 volts, perform the following steps:
Note:
If the starter solenoid is hot to the touch, use 9.5 volts in the above test. 9.0 volts should be used if the starter solenoid is at room temperature.
