If the starter solenoid is making a sound but the engine is not rotating, turn the keys witch to the OFF position, and
attempt to bar the crankshaft in both directions.
Bar the engine using the barring tool, Part Number 3824591.
If the crankshaft will bar over, attempt to start the engine.
If the starter motor cranks the engine, check the starter motor pinion gear and flywheel ring gear for damage.
If damage to the starter motor pinion gear and/or flywheel ring gear is found when replacing the components, make
sure to measure the distance from the starting motor mounting flange to the forward face of the front side of the
flywheel ring gear. Follow the measure step of this procedure.
If the crankshaft does not rotate or requires more than the normal effort to bar, check for an internal malfunction or
a problem with the drive unit and/or accessories.
If the engine cranking speed is too slow/will not crank at all and the engine rotates freely:
Make sure the wiring connections are clean, tight and not damaged.
Check the battery voltage. Refer to the OEM service manual and/or manufacturer for specifications.
Check the voltage at the starting motor during cranking. If the voltage drops more than 2.4-VDC on a 12-VDC system
and 4.8-VDC on a 24-VDC system , check that all connections are clean and tight.
If the cables are correct and the voltage drop exceeds the limit, replace the starting motor.
