i was workin on my 79 bronco and needed the battery out of the 89 f150 and when i was done i went to put it back but before i did i put new clamps on the wires and then when i was hooking them up i noticed they were a bit tight so i looked down and seen a hamer layin there that i was using to beat a dent out of my other truck, and had a dumb moment...when i hit the clamp on the battery i caught the fender and grounded the positive...dumb dumb i know...so now ill start the truck and the truck when keep trying to start itself....i changed the igition switch and relay already thinkin it was one of them... and i noticed that when the battery is disconected for a while it will go away for a little bit, hours mabey..so now im thinkin its the computer is ****ed cause itd reset itself which would explain why it might work at first by its odd why it would work bad again....this stupid mistake is comfusing, any ideas?

 

Well first off I would check all fuses and relays. Now from their I have no idea honestly.

 

I did something similar on my 98 durangoI replaced EVERY fuse, they all blew and she was fine...i found all sorts of hidden fuses my drivers feet and passengers feet

 

I checked all fuses in panel and gotta mention that when it keeps starting i can turn off switch and it'll keep goin till i take battery off,, would there be any fuses or relay to check that i didnt mention

 

bad relay?

 

it's the solinoid on the fenderwell, it's getting stuck in the on poss.if you take the two push on wires off the fron and it stil tries to crank it's that....one of the wires is the signal from the ignition switch(key)

you can check the wires with a test light. when you hit the key one should light up the test light and go back off when you release the key...if it dosent then the ignition switch is bad... you swapped it out...now do the $7.00 sol.

 

that was the relay i changed, and i already ran it without ignition wire on...thats why im so confused... i know i said it turns off when i disconect the battery but i imagine its just that the altenator wouldnt keep up to the draw on the battery when its turning over.....fustrating

 

Are you sure you didn't mix any of the wires up when doing the install?

 

ya im sure...i double checked and looked at my mustang to be sure...neg first, then positive and all other wires on the next one farthest away from battery..correct? same as on car anyway and its same set up....so odd
