Make sure the wiring connections are clean, tight and not damaged.
Check the battery voltage. Referto “ Batteries-Checking”.
If the crankshaft was not rotated to check the starting motor, bar the crankshaft in the direction of engine rotation to make sure the engine is free and does not have an internal malfunction.
If the engine is free, check the voltage at the starting motor during cranking. If the voltage drops more than 2.4
volts on a 12 volt system, check that all connections are tight. The limit for 24-volt systems is 4.8 volts.
If the cables are correct and the voltage drop exceeds the limit, replace the starting motor.
If the crankshaft requires more than a normal effort to bar, check for excessive load from the driven units and
accessories.
