Ignition run on 1989 Grand Wagoner

I'm working on my 1989 Grand Wagoner and as I'm starting the Jeep and let go of the key, it stays engaged. I can't figure out why. I've used a spare column to rule out the key ignition switch and lower column ignition switch.

I'm thinking that it could be possibly the starter relay, or NSS.

Anyone experience a similar situation with the later style system?

sounds like relay problem or wire going to starter solenoid is plugged into wrong spot on relay?

tap the starter with a BFH, if it disengaged, it is the starter....

Had that happened... it was in Ouray during one of the trail rides... fortunately it was not a hot day... so after the first encounter, then a repeat... I let the engine idle when we stopped for sightseeing!

Then drove to Montrose to buy another one.

The only weird wire on the relay is the one missing the jacket, I'm not sure how or when that happened. It's black and has something to do with the NSS. I unplug it and get nothing, I plug it back in and the starter just stays engaged a couple of seconds too long when I turn the key. Weird.



I have removed and cleaned up all terminals with grit cloth after taking pic. Wires seem to be in the correct locations. I don't want to buy a new relay for 50$ but will if I can't find another in my spare parts. This part was used from 88-91 or 89-91?

I'll give this a shot too. Thanks for the tip, I usually think of this on chevy starters not Jeep starters.
