Hold in Test of Solenoid
1. Disconnect the connector from “M” terminal.
2. Connect a 12V battery between “S” terminal and
“M” terminal.
CAUTION
This test should be done as soon as possible not to
damage the coil (in 10 seconds).
3. If the pinion is moving outward, the coil is normal,
if the pinion is moving inward, replace the
magnetic switch owing to open-circuit.
Return Test of Solenoid
1. Connect the connector from “M” terminal.
2. Connect a 12V battery between “S” terminal and
“M” terminal.
CAUTION
This test should be done as soon as possible not to
damage the coil (in 10 seconds).
3. When releasing after pulling the pinion outward, if
the pinion is returned to native position, it is
normal, if or not, replace the solenoid valve.
Performance Test (with NO-LOAD)
1. Connect a 12V battery to the start motor.
2. To operate the start motor with no load, turn the
switch ON. If the operating speed and current
measured are identified with the standard, the
start motor is normal. If the operating speed is
insufficient or the current is excessive, it is
because of excessive friction resistance. And the
low current or lack of operating speed is because
of faulty contact or open circuit between the brush
and the rectifier or between the welding points.
Speed Minimum 3,000rpm
Current Maximum 60A or less
