I have the SOHC 3000GT it comes stock with the 90 amp alternator, and I put the DOHC's 110 Amp in it. it ran for a month, and then stopped working. It was all corroded at one of the wires, so i looked it up and it seems the carwash i was going to sprayed my alt and caused the damage. I replaced it again, and this time its not workng at all. I replaced the fusable link, it came stock with the 120 amp fuse, and it didnt look damaged but i replaced it anyway, but still not working. Any suggestions? Im thinking maybe since the wire was corroded i didnt scrape it so the metal could touch or there is a short in the wire? Any help would be great! thanks!!!

 

Tesla...is your first name Nick? Electricity should be right up your alley. Like I say time and time again, get a factory repair manual, it is well worth the cost. You'd be amazed what you can do with it.

 

No my name is not Nick (LOL I wish i was as smart as him), and I don't know where to get one, there isn't a Mitsubishi dealership anywhere even remotely close to me.

 

UPDATE: I took it in to get it tested and they told me it was the voltage regulator, but to my understanding the voltage regulator is built into the 1999 3000GT's alternator... I'm getting a new alternator again, luckily there's a warranty on them so I'm getting free replacements. I'm gonna swap it out again when the weather clears up since I don't have a shop. :/ I'll let you all know how it goes, but please continue to comment.

 

Search on the web for a factory manual, stay away from those in the auto parts stores unless you can't find on on the web. Ebay motors may have someone who is selling one. Just do al lot of web searching.

I have not used them, but I have heard that Mitchell is a good one to use. Here is a link that someone talks about the different manuals and services.

Voltage regulators, when they are integral with the alternator are usually attached to the back of the alternator case, either outside and sometimes inside.

 

alright, Ill check out that site right now. Thank you very much for the help. Feel free to check out my pictures and leave comments!

 

ALRIGHT!!! I was in replacing the alternator again and it turns out one of the wires was horribly corroded from before. So I lightly wiggled the wire because it definitely didn't look healthy and it crumpled in my hand like charcoal. I cut about an inch off of the wire, stripped about an inch bare, and re-crimped a new eyelet so i could connect it properly. It works just like before! This is the first car I've started really doing my own work with. It feels good. Any way, thanks for all the comments and tips!

 

Just to let you all know, it still works fine. That was the problem. If you go through a car wash make sure you know whats under your hood and where its at. The undercarriage wash destroyed my alt and cost me a lot of time. Any ways it was a learning exp and glad i learned as much as i did. Thanks again for the comments.
