SWITCH ASSEMBLY Subaru Impreza WRX GH

SWITCH ASSEMBLY

Using a circuit tester (set to "ohm"), check that there is continuity between terminals S and M, and between terminal S and ground.

Also check to be sure there is no continuity between M terminal and B.

Terminal/Resistance

S - M/1 ohms or less

S - Ground/1 ohms or less

M - B/1 Mohms or more

Scheme 22

Scheme 23

1. Using a lead wire, connect the S terminal of switch assembly to positive terminal of battery, and starter body to ground terminal of battery. The pinion should be forced endwise on shaft. NOTE: With the pinion forced endwise on shaft, starter motor can sometimes rotate because current flows, through pull-in coil, to motor. This is not a problem.
2. Disconnect the connector from M terminal. Then using a lead wire, connect the positive terminal of battery and M terminal and ground terminal to starter body. In this test set up, the pinion should return to its original position even when it is pulled out with a screwdriver.
