28 CHAPTER TWO Ohmmeter Ohmmeter Solenoid (S) terminal Starter motor Solenoid (M) terminal Starter motor the engine. Once the engine has started and the start switch is released, the slave solenoid is de-energized. Without current to hold the solenoid in position, the starter motor overrunning clutch disengages the starter pinion from the flywheel. 3. Repeat Step I. If the starter running speed is still too slow, replace the starter. On-Boat Testing Starter solenoid clicks, starter does not run Two of these procedures require a fully charged 12-volt battery, to be used as a booster, and a pair of jumper ca- bles.
Use the jumper cables as outlined in Jump Starting, Chapter Nine, following all of the precautions noted. Dis- connect the wiring harness and leads at the rear of the al- ternator before connecting a booster battery for these tests. This will protect the alternator from possible dam- age. I. Clean and tighten all starter and solenoid connections. Make sure the terminal eyelets are securely fastened to the wire strands and are not corroded. 2. Remove the battery terminal clamps. Clean the clamps and battery posts. Reinstall the clamps and tighten them securely. 3. If the starter still does not run, connect the 12-volt booster battery to the engine's battery with the jumper ca- bles.
If the starter still does not run, replace it. Slow running starter Starter solenoid chatters (no click), starter does not run I. Connect the 12-volt booster battery to the engine's bat- tery with jumper cables. Listen to the starter running speed as the engine is cranking. If the starter running speed sounds normal, check the battery for loose or cor- roded connections or a low charge. Clean and tighten the connections as required. Recharge the battery if neces- sary. 2. If starter running speed does not sound normal, clean and tighten all starter solenoid connections and the battery ground on the engine. 1. Check the S terminal wire connection at the starter so- lenoid.
Clean and tighten if necessary. 2. Disconnect the S terminal wire at the starter solenoid. Connect ajumper wire between this terminal and the posi- tive battery post. 3. Try starting the engine. If the engine starts, check the key switch, starter switch and the system wiring for an
