92 cherokee changed the alt. now it wont start . Every thing comes on when i turn the key on but it wont crank the starter over ,it not gretting juice to the small post on the selinoid. Could i have gottin a bad alt. ? Does curent go throught the alt before it gets to the starter? Anyone have any ideas as to what happened. Oh also the next day after i installed the alt the batt. was dead . Didnt have any problems with these things before this.

Sounds like you have a short somewhere. Check your wires and check your fuses.

Would start even with a bad alt. right after you put it in. You messed up something go back over everything you touched might have touched etc. You did unhook the battery while doing this so you didn't short anything out when unbolting the alt. and hit metal with the wrench right?

jaycool47

no i didnt unhook the batt. and yes i did get sparks than i unhooked the batt. So what could i have shorted out. I can jump it at the starter and it will start.Just wont start with the key switch.

pull the starter relay, & swap it with a like relay in the fuse pannel... just for giggles

Always disconnect the battery. But, at least you know now.

OK i will try swaping relays tonight when i get home. thank for the help .let you all know if that was it.

thats what happend to me is the relay went out, so I just wired up a push button start!

jaycool47

Why cuoldnt you just replace the relay ?

builtnotbought89'

Because that cost money, & for a trail rig push button is cooler!

jaycool47

ok gotchya . Hope i can get home early enough to check that relay tonight.

Well no luck with the relay so what next .Im still wondering if i got a bad alt i have been told that the starter cucuit goes through the alt but without a wire schmatic i dont know. Does anyone have one they could look at and let me know for sure or maybe email me one. Please.
