CHECK STARTER SOLENOID VOLTAGE:
• Dial 70 into TEST SELECT and press TEST.
• Engage fuel shutoff switch and crank the engine and
observe the displayed voltage.
• Is the starter solenoid voltage above 18.5 volts?
6
CHECK BATTERY VOLTAGE WHILE CRANKING:
• Dial 67 into TEST SELECT and press TEST.
• Engage fuel shutoff switch and crank the engine and
observe the displayed voltage.
• Was the battery voltage above 19 volts while cranking?
YES
NO

YES
• If starter resistance was high in step 2, check positive battery cables
and connections to starter solenoid. Repair as necessary
(WP 0125 00). If OK, replace starter motor (WP 0091 00).
• If GO message occurred during Starter Circuit Resistance Test
in step 2, check switches and wiring to solenoid. If OK, replace
starter motor (WP 0091 00).
