(3) If dirt and corrosion have accumulated on the battery, it should be cleaned with a solution of
baking soda and water. Be sure none of the solution enters the battery cells.
(4) The starting circuit wiring should be inspected to be sure that all connections are clean and
tight and that the insulation is sound.
(5) A voltage loss test should be made to locate any high resistance connections that would affect
starting motor efficiency (see Chart 1).
(6) The starting motor should be operated for a few seconds with the ignition switch off to make
sure that the pinion engages properly and that it turns freely without binding or excessive
noise. Then the engine should be started two or three times to see that the pinion disengages
properly when the engine is turned off.
B. Starter Control Circuit
(1) Inspect the control circuit wiring between the battery, solenoid and manual starting switches for
breaks, poor connections and faulty insulation. Tighten all connections and make sure solenoid
is firmly mounted and makes a good ground connection.
(2) Check the voltage loss across the switch contacts during normal starting. If loss is in excess of
0.2 volts per 100 amperes, the solenoid should be replaced.
(3) If solenoid fails to operate when the manual starting switch is turned on or if it fails to release
when the manual starting switch is released, it should be removed and tested to specifications.
If either opening or closing voltages are not to specifications, replace the solenoid.

A. Removal
CAUTION: TO PREVENT SHORT CIRCUITING, DISCONNECT THE GROUND CABLE FROM
THE BATTERY BEFORE REMOVING THE STARTER FROM THE ENGINE.
(1) Disconnect the electrical leads from the starter terminals.
(2) Remove mounting bolts.
(3) Remove starter.
B. Installation
(1) Position starter on engine.
(2) Insert mounting bolts and secure.
(3) Connect the electrical leads to the starter terminals.
(4) Reconnect the ground cable to the battery.
