1994 GMC Suburban 2500 Q&A

1994 GMC Suburban 2500 Question: My starter has three wires, how do I hook it up.

Have changed the starter and fly wheel. Think I have starter hooked up wrong. It has three wires. Also, when hook up batteries to try to start, batteries spark and Glow plug stays on all time. Think I might have starter connected wrong -
Answer 1
you have large cable which hooks to large terminal thats easy, the starter hit wire goes to small terminal on solenoid on start side.the solenoid should be marked i for ignition and the other wire goes to the other terminal marked r for run. hope this helps -
