MJ'87 Posted October 29, 2008 Share Posted October 29, 2008 don't understand it. :dunno: the MJ won't even crank, and yet the battery is fully charged. it will still run perfect if it is bump started, but thats it. i just put a new starter in it this morning and it still won't crank :wall: this is a real :hmm: Link to comment Share on other sites More sharing options...
FxRacing282 Posted October 29, 2008 Share Posted October 29, 2008 okay so if the lights and everything works then its MOST LIKELY a key switch problem. there is a rod that runs down the colum. check to see if it moves when you turn the key.

Pete M Posted October 29, 2008 Share Posted October 29, 2008 Does the starter relay make an audible click? Link to comment Share on other sites More sharing options...

FxRacing282 Posted October 29, 2008 Share Posted October 29, 2008 sounds like you have not enough power going from the starter to the battery. you can test this by taking a multimeter and set it to the ohm setting (looks like a horseshoe). place one lead on the positive battery cable at the connection on the battery and the other at the other end of the cable on the starter. then turn the key to the start position and see what your ohm reading is. it shouldnt be a double digit Link to comment Share on other sites More sharing options...
MJ'87 Posted October 29, 2008 Author Share Posted October 29, 2008 it was like around 0. and there's 12.7 volts also Link to comment Share on other sites More sharing options...
FxRacing282 Posted October 29, 2008 Share Posted October 29, 2008 okay, maybe its voltage I'm thinking of, not ohms. its been a while since ive had to do it. Link to comment Share on other sites More sharing options...
Akula69 Posted October 29, 2008 Share Posted October 29, 2008 Another way to test the starter is getting the current is attach a wire to the positive terminal and them briefly touch it to the positive terminal of the starter (don't hold it there!). Could be that the solonoid is bad on the new one. Link to comment Share on other sites More sharing options...
KillerCOM Posted October 30, 2008 Share Posted October 30, 2008 your talking about a voltage drop test. put your DMM on the DC volt setting and put the positive lead on the starter post. then the negative on the negative post on the bat. if you don't have any voltage the fusible link in the starter lead has been fried the easies way to check if it's been fried it grab it and see if it stretches.

BLHTAZ Posted October 30, 2008 Share Posted October 30, 2008 I think your on to it with the battery cables. Check them out good as I had troubles and when I got in to it, I found this... Link to comment Share on other sites More sharing options...
MJ'87 Posted October 31, 2008 Author Share Posted October 31, 2008 ALL FIXED! it was weird: "spontaneous" green fuzz. i was on my way to school on monday, stopped to get gas, started back up just fine. about six hours later no start :dunno: . weird how it all-of-the-sudden happened. thanks for everyone's help in diagnosing the problem :bowdown: Link to comment Share on other sites More sharing options...
