Starter relay on 71?

Post by Analog »

I don’t see a starter relay on my 1971 wagoneer with a Buick 350. I see a voltage regulator and a horn relay. The starter has the solenoid attached to it. The starter continues to turn over even with the key removed. It only does this on the second or third turn over attempt. I have to pull the negative battery cable to stop it. I assume the solenoid is bad but wanted to check if it might be a relay issue. The neutral safety switch seems to work as it won’t start unless it is in park but I might have to slightly move the gear selector just bit to get the starter to engage.

The relay is built-in to the GM/Delco type starter. That cylinder on the starter is a solenoid that both connects the battery cable to run the motor and throws the drive gear into the flywheel. Other Jeeps will have the Ford-type solenoid on the fender well (and a Ford type starter) but the Buick does not.

A very common service item. Your local parts store will have one or can get one easily.

The gear shift action to start is also common. Adjustable at the NSS. Your TSM should show it.

Great. Thanks for the clarification. I also just ordered the TSM.

Also, the starter is the same as Chevy V8 with 153 tooth flywheel (inline bolt pattern).

I have the Ford relay on all my cars now. Easy job, just have to jumper the contacts on the starter.
When my old Elco starter stuck, it turned out to be a worn out ignition switch.
