2.1 Inspection before disassembling starter

2.1.1

No load test

Use as thick a wire as possible and firmly tighten each
terminal.
When detecting the rotation at the tip of the pinion, be
careful, as the pinion pops out during operation.
(1) Connect the starter to the circuit as shown in the
illustration.
(2) In normal condition, the pinion pops out when the
switch is turned ON, and the starter rotates at or more
the specified rotation speed.
If the terminal voltage, current or rotation speed does
not meet the standard, disassemble, inspect and repair
the starter.
