Brush Spring

Use spring balancer to measure the spring setting force
when remove the spring from the brush.

Standard: 17.65–23.54 N (38.9–51.9 lb)

Limit: 11.77 N (25.9 lb)

Magnetic Switch

Temporarilly connect the magnetic switch between the
overrunning clutch and housing.
Perform the steps described below in 3 to 5 seconds.

3. Return test

Connect the ground (-) to terminal 50 and magnetic
switch body.
Verify that the pinion pulls out when the battery (+)
pole is connected to terminal C and the pinion pulls
away when the lead wire is disconnected from
terminal 50.
