I have an 89 cherokee and i put in a new alternator last nite. hooked up the right cables in the right spots on the alter nator as it was pretty much self explanatory. threw a new belt on, tightened it up, and hoppe in to start it up and see how it was gonna do.
except i didnt have enough juice in the battery to start and it was 11:30pm, so i waited til today.
just rolled it out of the garage for a jump. popped the hood and the underhood light didnt come on. so i figured the battery drained itself over night. we hooked up the cables to my dads silverado then hooked em to my jeep. red on red. black on black. the way youre supposed to. (i guess i could have found a ground on my jeep...)
anyways i hopped in, turned the key, heard a click, and had no power. ANYWHERE.
no radio, lights windows.... ABSOLUTLEY NOTHING. and definatley not a running jeep.
Other than the alternator replacement the same thing just happened to my 89. I pulled the battery and had it tested. It had a bad cell. Replaced it (free - gotta love warranties) and off I went. Hopefully it's your only issue.
thanks for the input man. well too bad i bought this cherokee and it already had a battery in it. i have no reciepts for the battery or anything. dont know where it was bought. the date that the battery was put in the jeep isnt even recognized on the battery. someone forgot to mark it.
yeah batteries can die to the point of no return. which it sounds happened to you. might want to get it tested like suggested. or maybe just clean the terminals really well. mine used to randomly have no power like you are describing, due to a bad/dirty/loose battery cable
Completely stock, and keeping it that way...
this is dumb tho because before i replaced the alternator everything worked fine. never had any battery troubles...
Sorry man, i wasn't trying to be a smart ###, but ive worked on vehicles before, and SWORE whatever I did to it had to be the problem after i was done, and it ended up being something completely different. You just gotta start simple, with stuff like are you sure the computer is plugged in, is there there gas in it, etc?
Do you or your dad have a volt meter? see if you have 12 volts at the battery.
If battery voltage is low try charging the battery again, when batty is fully charge leave it set over night and check voltage again. If low, buy new battery.
When jumping a dead battery, sometimes you have to leave the cables hooked up awhile before trying to start the jeep. The cold outside it is the longer the wait.
