Morning Sickness

Within the past three days i changed out my ignition coil, and solenoid because the engine was having a difficult time turning over completely. I came to find that the solenoid had an unhealthy amount of corrosion. Everything seemed to be ok until this morning when it sounded as if the starter had a short and it was trying to start the engine when it was already running. I couldn't get the engine to turn off while this was happening so had i had to flip the kill switch. Any ideas on what might be causing this. New starter, battery, ignition coil, and solenoid within the last week.

 

Battery cable at selonoid hitting start post?

 

Bad key switch?

 

I would check that first.

 

So i ended up replacing the key switch but that didn't seem to fix the problem. The noise is definitely coming from the starter and the flywheel coming into contact with eachother at the wrong time. For now the sound has gone away but im afraid that i'll be on the road and it will happen again. If anyone has any other ideas it would be greatly appreciated. Thanks again for the other suggestions made.

 

Sounds like you could have more than one problem. The most obvious source would be the solenoid, which you've replaced.

These's an extensive diagnosis, repair and troublehooting section for the starting system in the factory service manual. If you don't have a manual, I'd suggest you get one. Reprints can be purchased at http://www.thejeep.net/catalog/prod...84&PHPSESSID=c1955ad18158626815d52f53f13df2fe and other places on the net.

There's a '72 manual online at www.c104.net though it's a really slow link.

If the starter is hanging up on the flywheel, there could be several causes, from a worn-out starter to loose bolts. Easy to remove the starter - the manual has instructions on starter inspection and repair.

 

I had a Jeep along time ago that I ran in the mud alot. One day we were out playing in the river. Went to start it, the engine started but the started was still engaged like I had the key turned to start it. The only wat to stop it was to diconnect the battery. The only thing we could find was that dirt and mud got into the solenoid and was causing it to stay engaged. Laying in the river I unbolted the started and rinsed the starter assembly in the river. Re-installed it and I never had any more problems.

I would look at the solenoid area to see if it is sticking. Maybe some lubrication is needed.

 

I just got towed... again. I was talking to the driver of the tow truck and he was saying the same thing that it was either the solenoid is faulty or the battery is weak. Considering the battery is brand new i think im going to try the solenoid again. Both the solenoid and the starter are Kragen specials so I'm going to try another company, something of more quality.

 

Sounds like your towing the little black cloud that Linus used to have.

Might fill out your profile, maybe someone nearby could give you some help. Either of those components is fairly easy to test for proper operation before replacing. I have a couple of AMC starters and at least one solenoid and ign switch you could try if we were close enough to make it feasible.

However, after looking closer at your Avatar I doubt we're very close geographically.

New solenoid (for the third time)... not the problem.
New starter (for the third time)... not the problem.
Starter and ignition wires fused and singed to oblivion (exhaust manifold)...
Finding the problem and fixing it... priceless.
Blue 73 is on the road again, thanks for the help!

 

Glad you found the problem.
Time to enjoy it.

 

did u change ur starter if so they can have ship u the wrong one and than it could hi the teet of the ring gear when still running.

when a starter get old it often run slower and if u check it will be very hot which mean it suck a lot of juice trying to cranck the engine. it also can be the sping which push the bendix back which could be break or tired.

the mud in the starter i also had experience it but the worst thing is that i got it fire back by pulling it with an other jeep it went until i park it. ithen told myself i ll change the starter this week.... when i start it back the clutch did not work no more to much mud in it i had to remove the transmission cleaning all the clutch and pessure plate and bolt it back on lol a lot of fun for a single but challenging mud hole big al

 

i forgot something i then seal the belt housing real good so it never happen back lol
