Addicted To Boost Posted March 24, 2009 Author Report Share Posted March 24, 2009 sounds like a fusible link to me What do I do about that, and what exactly is a fusible link? Quote Link to comment Share on other sites More sharing options...
spiderw31 Posted March 24, 2009 Report Share Posted March 24, 2009 After reading through this thread, I remembered I had read somewhere that if one of the terminals on the alt doesn't see a voltage, the alt won't charge. I seem to remember that the terminal in question is connected through the voltage warning light, and that if the light burns out or the circuit is otherwise interrupted, the alt will no longer charge. Unfortunately, I can't seem to find the article now, so I may be remembering something completely different, or just flat out wrong. In any event however, I found some interesting troubleshooting that can be used to determine wiring issues here: http://www.alternatorparts.com/cs130_sbpage3.htm Hope this helps!

Addicted To Boost Posted March 24, 2009 Author Report Share Posted March 24, 2009 Interesting.. when I was driving home and I noticed my voltage dropping, my battery light never did come on I think the bulb may be burnt out. As for the link, I had my alternator bench tested this morning, and it checked out good as well. Quote Link to comment Share on other sites More sharing options...

When you turn the key on and the "bulb check" runs with all the lights on the dash does the battery light light up?) Quote Link to comment Share on other sites More sharing options...
Garrett Powered Posted March 24, 2009 Report Share Posted March 24, 2009 did you check the fusible links going from the alt to the starter? down off the starter? Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted March 24, 2009 Author Report Share Posted March 24, 2009 I'll ask again, what are fusible links and what do they do? I don't know what I'm looking for. Quote Link to comment Share on other sites More sharing options...
94GPGTP Posted March 24, 2009 Report Share Posted March 24, 2009 they are orange.. go look at your tgp and you will see 2 orange leads coming off the aux terminal going to 2 red wires which lead to the PMIII the orange leads.wires that turn into red are the fusiable links.. so then therefor you will be looking for the exact thing on your 91... hope that helps Quote Link to comment Share on other sites More sharing options...
94GPGTP Posted March 24, 2009 Report Share Posted March 24, 2009 the orange wire going across the sender is the fusiable link going to the starter so thats where its at.. just minght be another by the aux but not 100% sure Quote Link to comment Share on other sites More sharing options...
Garrett Powered Posted March 24, 2009 Report Share Posted March 24, 2009 a fusible link is a short length of wire that gets crimped in line with some of the main wiring on your charging system just in case something gets shorted out they are designed to melt away clean to keep the car from burning to the ground. you can go to the parts store and buy new ones and when you replace them you should cut off the whole length of the old one and not reuse any of it. there should be two of them going to the starter and all the ones off the aux post. the ones in that picture are what I was talking about. I would replace them if they got chunks of the wire jacket missing. I usually just put new ones on when I swap out starters anyway since they are cheap and easy to replace.

Pontiac6KSTEAWD Posted March 24, 2009 Report Share Posted March 24, 2009 I would suggest taking a new piece of wire from the alternator, and running it to the battery directly. It will be the easiest, and one of the more common issues of the charging systems. Quote Link to comment Share on other sites More sharing options...

It will be the easiest, and one of the more common issues of the charging systems. I did that just now. I ran a 4 GA wire directly from the alt to the battery, and it didn't fix it. What else could it be? Quote Link to comment Share on other sites More sharing options...
89GP_SE Posted March 25, 2009 Report Share Posted March 25, 2009 The way I test for bad fuseible links is grab like 2 inches at a time and give a light pull, if they dont stretch out they are good, they they stretch out easily they are bad. have you checked the underhood fuses/relays and maxifuses? Does your battery light come on? Quote Link to comment Share on other sites More sharing options...
spiderw31 Posted March 25, 2009 Report Share Posted March 25, 2009 I know they are vague, but the instructions in the link I posted should help in sorting out a wiring problem. Also, see if you can get your hands on a wiring diagram of the charging system. I'd post the one in the back of my Haynes manual, but my scanner doesn't work At this point, I suspect you'll find either corrosion / broken wire that ties into the plug on the alternator, or the battery bulb is burned out (assuming you car has that, and I can't double check on mine since it has no batt in it right now ) Quote Link to comment Share on other sites More sharing options...
TGP5sp90 Posted March 25, 2009 Report Share Posted March 25, 2009 I'm getting 9.90 volts at the battery. OMG Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted March 26, 2009 Author Report Share Posted March 26, 2009 Could this be anything ECM related? When we were doing the coolant flush last weekend, my buddy was cleaning the engine bay (and around the ECM) when I had the coolant overflow tank off and was cleaning that out..

spiderw31 Posted March 26, 2009 Report Share Posted March 26, 2009 I wouldn't say ECM related per se, but according to the wiring diagram, one of the leads that goes to the alternator connects to the "right side electrical center". From there, it connects to the indicator and instrument panel. If I'm not mistaken, a break in that line would keep the alternator from charging, so yo may be on the right track.

Addicted To Boost Posted March 28, 2009 Author Report Share Posted March 28, 2009 I fixed it! Turns out, the two "IGN" fuses in my relay center on the passenger fender were both blown. I replaced them, and the car works perfect again! Thank you Jim (TGP5sp90) and others for all your help! Quote Link to comment Share on other sites More sharing options...

TGP5sp90 Posted March 28, 2009 Report Share Posted March 28, 2009 Sometimes it does take a dodge guy to fix something, thats because their always failing No problem Nick, glad to here you got it fixed Quote Link to comment Share on other sites More sharing options...
dogginred90 Posted March 28, 2009 Report Share Posted March 28, 2009 If you are talking about this Dodge guy. I dont think so, I am GM all the way. Just happened to be helping a friend out and found those blown fuses. And if you are not talking about me I am sorry, I posted about the fuses on tgpforums. Glad you got her fixed Nick.
