Solenoid problem

85 CJ7 258 5 speed. I am trying to get my brothers Jeep back on the road. Working out some minor problems. RIght now I cant get it to start with the key. I can jump the solenoid, and it fires right up.

My brother couldnt get it to start once, so he replaced the solenoid. It still didnt work. Not sure what the deal is. I hate working behind people, because you dont know what they did to it.

I get voltage from the battery to the solenoid.
When the key turned forward (accessory position)I get voltage from the red wire on the side of the solenoid. When the key is turned to start I get voltage to the blue wire. I get no voltage to the starter wire itself. There is a nipple on the solenoid between it and the inner fender that has no wire going to it???? I grounded it momentarily, and the solenoid buzzed at me? What is supposed to plug into there??

I'll see if I can post a pic.

Thanks
Brian

Nipple?? Well maybe it's a screw terminal. There should be two small terminals and two large terminals. You have three out of four by default connected correctly.

From what you have described the original solenoid failed and was replaced by a slightly different version of the same type solenoid that does not have the coil side grounded internally.

If I remember correctly one of the funny things about the AMC solenoids on manual transmission versions was that the coil ground was provided internally. Simple to jump that "unused" terminal to ground and it should start.

The solenoid is simply a relay, the two small terminals are the low current coil (small wires) and the two large terminals connect the battery to the starter (big wires) when the coil is energized.

Looks to me like you are one small ground wire away from driving that Jeep.

Good Luck

Re: Solenoid problem

Thanks for the reply. When I do ground the nipple it starts....regardless if the key is on or not. I tried switching the smaller wires to the nipple, but still wont start. Could that nipple be for some kind of safety switch? I dont think the clutch has a safety switch, maybe they gave my brother the wrong solenoid??? The nipple has voltage to it when the key is turned forward.

THanks,
BRian
