#98 of 130 1997 Jimmy wiring diagram source by mrtbob

I have a 1997 GMC Jimmy 2WD 4.3L engine that I need a wiring diagram for. I bought a Haynes repair manual , but it doesn't seem to come close to covering my vehicles wiring. My jimmy had a fire under it at some point in its past and melted a large switch assy on the side of my tranny. It seems to select lights (reverse etc) among other things, but its all kind of a mess now. Where can a guy obtain this info. Thanks.

#99 of 130 '00 jimmy - Something's draining the battery by edortizr6

I think something is draining the battery. I replaced the battery and the alternator but that didn't help. I checked the fuses and they all look ok. I was thinking maybe it's the positive cable on the battery, but I'm not sure. I'm not familiar with the electrical system. I just tried to start the truck and there was power. As soon as I turned the key everything went dead. I'm going to get this battery charged again and take it from there. If anyone has any ideas, I'ld love to here it. Thanks in advance.

you have a bad connection somewhere, you can check the positive post to make sure it is not broken, that happened to me once, or your possitive cable is corroded somewhere down the line.

#102 of 130 2001 GMC Jimmy - No electrical power anywhere by chris_kreiner

My brother was driving his Jimmy the other night when without warning he lost all electrical. He didn't even have a slighty flicker of power once it died. I asked him if he smelt anything hot like there was a short somewhere and he said NO. I checked his battery and it had more then enough power to turn on dome lights yet they wouldn't work. Everything is dead. We don't know what the problem can be, we looked at the ignition switch and I don't see anything wrong with it but not quite sure how to test it. What would cause this vehical to just loose electrical power without any warning?

#103 of 130 same problem, no power. by dludwick

My son's 97 Jimmy has the same problem as above...no electric power anywhere. The other night we had to tow it home after it died from what we thought was a bad alternator. Headlights going dimm, stalled out, wont start, and when the jumper cables were removed it died. So the next day we spend some rent money on a new alternator and battery. Now theres nothing. No power anywhere. I've checked all the fuses I could find, and we took the covers off around the ignition switch and no power to any of the big wires going to the switch. We cant afford a mechanic and if he dosen't have it monday we're screwed....any ideas???
PLEASE HELP!

Well after my original post I took the battery to be checked. Although it was a new battery, it still needed a charge. I figured something was killing the battery. Since I charged the battery I haven't had a problem. I did figure out that if the break release was not pulled hard enough, the dome light would stay on. That might have been what was was killing the battery in the first place. I don't think that's your problem though.

well after a $190 repair bill we were informed that we had left a wire unhooked from the alternator...when we put the new one on it got trapped under it and we couldent see it.....sucks...
but thanks for the help guys.
