Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Hold-In Test
Disconnect field coil wire from terminal "M" of solenoid. Apply battery voltage to terminal "S" of solenoid, and ground starter case. See Fig 1. Solenoid plunger should pull in. If pinion drive remains out when plunger is pulled in, hold-in circuit is good. If pinion drive moves in or moves back and forth repeatedly, hold-in circuit is open. Replace solenoid.
