TEST OR INSPECTION
2. ENGINE CRANKS BUT FAILS TO START ABOVE 50°F (18°C) - CONTINUED.
Although KEY SWITCH must be on and battery ground cable connected to test electrical circuit
voltage, turn off KEY SWITCH and disconnect battery ground cable before doing resistance tests
or replacing parts. This will keep you from getting shocked and prevent damage to parts and
Do not crank engine for more than 30 seconds. Allow starter motor to cool for 2 minutes between
cranking attempts. Cranking too long can overheat and damage starter motor.
Remove fuse (1) and check for broken condition as follows: Set multimeter, to ohms scale and
adjust to 0 ohms. Connect red test lead to fuse end (2) and black test lead to fuse end (3).
Check for 0 ohms on multimeter. Disconnect test leads.
If multimeter reads no continuity, replace fuse (1).
Check for 11 to 13 vdc at NO terminal (4) on oil pressure switch (5) as follows: Set multimeter to
20 vdc scale. Connect red test lead to NO terminal (4) and black test lead to ground. Have
assistant rotate KEY SWITCH (6) clockwise to on position and press ENGINE START button (7)
for 5 seconds. Check for 11 to 13 vdc on multimeter. Have assistant rotate KEY SWITCH (6)
counterclockwise to off position. Disconnect test leads.
If multimeter reads no voltage, go to step 28.
Check 19F wire (8) from fuse panel (9) to NO terminal (4) on oil pressure switch (5) for broken
condition as follows: Pull wire connector (1) from fuse panel (9) and, using 3/16-inch flat-tip
screwdriver, loosen screw (11) and take off 19F wire (8). Set multimeter to ohms scale and adjust
to O ohms.
