F510 & F525 Starter – BENCH TEST SOLENOID DRIVE STARTER

NOTE: Perform bench test before disassembling starter motor to determine cause of problem.
IMPORTANT: Never operate motor longer than 20 seconds. Allow at least two minutes for cooling and battery recovery before operating again. Overheating, caused by excessive operation, will seriously damage starting motor.
1. Disconnect battery leads from battery, negative (—) lead first.
2. Remove starter from engine.
3. Connect 12-volt battery (A) to starter battery terminal (B) and starter frame (C) using heavy duty cables.
4. Connect remote start switch (D) between switch terminal (E) and battery terminal (B).
NOTE: A short piece of wire with a small alligator clip on the ends will allow a more positive connection at the switch terminal.
5. Activate remote start switch, starter should engage and run.
IF SOLENOID CHATTERS; hold-in winding is open-circuited.
IF NOTHING HAPPENS; either the solenoid pull-in winding is open-circuited or mechanical parts are sticking.
IF SOLENOID ENGAGES, BUT MOTOR DOES NOT
RUN; check solenoid switch continuity, brushes, armature and field windings.
NOTE: Solenoid cannot be repaired, if faulty it must be replaced.
