CJ7 starter / solenoid
Hey y'all;
I have a '79 CJ7 that I'm slowly replacing, piece by piece. I drove to my Dad's today, and my Jeep wouldn't start. I ended up popping the clutch to get it to run, but couldn't take it to work since I didn't have a place to run it downhill to pop it again. It's got a 258 V6 original engine, 3 spd manual. The starter turns fine, plenty of juice in the battery. It won't engage with the flywheel to start the engine. We've had torrential rains (7 1/2 inches in a day) and the jeep was outside. I'm assuming the solenoid got wet and isn't engaging the armeture on the starter. I bought a new starter to make sure it wasn't the problem, but does the same as the old one (its the original starter, so before I replaced anything else, I assumed that it was the starter, and didn't have a chance to take it off and check it before I went to the auto parts store). Any chance it's anything other than the solenoid? The flywheel is clean, no chips in the teeth, and it does not sound like the starter is mating with the flywheel. Have I guessed it right, or am I missing something? Thanks, -K |

Use a jumper cable to momentarily connect the starter
to the positive on the battery. If the engine cranks normally then suspect the solenoid. Solenoids do actually die. I had to replace the one in my 87 a few months ago. > wrote in message ups.com... > Hey y'all; > I have a '79 CJ7 that I'm slowly replacing, piece by piece.

Your 'inline' 258 has a relay and a bendex, no kicker solenoid like a GM
would have. If you have a V shaped engine, my fix below isn't likely valid and you really need to find out what engine is in there..... You should be able to 'bench test' the new or old starter using booster cables. I hold the starter down with my foot and hook up the positive connection to the battery positive, then take the other booster cable from the battery negative and touch the starter case. The starter will spin up and the gear will shoot out to the end. If the gear doesn't shoot out, the starter is bad or you have a really low battery. The 'solenoid' is on the fender and costs less than ten bucks. It does get bad connections that usually just result in a click, not the starter spinning free although it can happen with a dirty connection. It can be cleaned or replaced.

It took two Bosch and one Champion starter to finally get a rebuilt that
started my 81 CJ, try another rebuilt. > wrote in message ups.com... > Hey y'all; > I have a '79 CJ7 that I'm slowly replacing, piece by piece.

It's a 6 cylinder, and the manual refers to it as a V6, I'm assuming they do because it's a 6 valve engine, no the placement of the cylinders. > > The starter turns fine, plenty of juice in the battery.

Ok, so get this. I get the new relay/solenoid, install it, nothing. Huh. Reinstall the old, same deal. Try bypassing the solenoid, nothing on the starter (old starter). Plenty of amps in the battery to turn it over. Try bench testing the old starter; nothing. Try bench testing the new starter, nothing. What gives? They both spun last night when I was having the difficulty, now I try and bench test them and they won't go? New or old? Yes, I hooked it up correctly with the pos / neg. Weird. If I have the ignition in the acc position (full counterclockwise) with the old solenoid, I get some juice to the radio, but nothing else. No lights, no nothing else. It;s the original harness, and up until I had difficulty, no problemo. Everything worked. Now, nada. Any ideas, hints, etc? I am going to return both the solenoid and the starter, but dagumit, wish I knew the answer. I checked the fuse blck, all fuses are fine. If it were the ignition, I assume bypassing the solenoid would turn the engine over? Help please before I have to drag it down the road to my repair guy. > > > > Any chance it's anything other than the solenoid?

You are either doing something radically wrong or there is something
radically wrong.... For starters you have the wrong 'book'. There is no V involved in the 258. It is a normal straight six engine with 12 valves, 2 per cylinder. From all the strange symptoms I would have to figure you have to have a dead battery connection between the cable clamp and the battery post. Nothing else makes any sense. I would be removing the battery cable clamps and giving them a good clean, then I would be at least checking the battery with a meter to see how dead it now is. Don't forget the solenoid has to be grounded to turn on and on which side you took the old wires off from. There should be at least 3 loop connectors on the solenoid battery side post and only one on the starter side with 2 small wires on the small posts.

CJ7 starter / solenoid
But it isn't a 6 valve engine either. It's a 12 valve engine.

But the 1947 GMC six is thirty two valve.
