Maintenance & Repairs - Oil choices, timing belt, setting timing, CV boot replacement, alternator servicing, fuse/relay checks, and other basic maintenance, repair and diagnosis discussions.
Maintence free doesn't usually mean reliable.
Took the alternator in for a check where I bought it (no Autocrapzone place for me, but a well-known alternator repair shop here in my town..) and it checked out good...but he did mention to me on checking that ALT fuse.
Guess what, he was right. that 80A alternator fuse-even though it looked good, was wide open with one leg broken off way deep inside the fuse.
Went out to a yard and yanked a couple of these fuses from busted up DSM's.
NOW, here's the surprise: those fuses are NOT plugged in as with the rest-they are bolted down by two bolts on each side of that fuse. Two, 10mm bolts is what holds thus fuse down in that block mounted next to the passenger shock tower.
Put that new fuse in, put everything back together and the Mitsu was running like a top and charging very well with the ALT putting out 13.9vdc by my digital VOM.
Something to think about.
Is yours doing the crap where it only does this when you run ac? I had mine doing that in the GST turns out the alternator was putting out just enough to charge the battery but if I turned on the ac it was actually putting out only enough to keep the battery from going dead.
What ^^ said. When you asked someone for an alternator load test, a lot of retards at shops will usually hook up a voltmeter to the battery terminals while the car is running and say, "yup, alternator's workin man". This is not a load test.

Where did you get this new alternator from?
If you suspect the alt only an alt/starter repair shop (see yellow pages) can fully test it. Auto stores have worthless testers.
....and that is what my DSM was doing before I did put a new ALT in .. battery and brake light would flash off and on on occasion.
Took it off, took it to a respectable ALT shop here in town (won't get caught showing my face at Autozone) and they told me that my ALT was signing its death warrant.
Got a rebuilt one from them and have been good since.
If you go out to yards to find busted up DSM's for that 80A fuse and have been all taken, look at other Mitsus, for some of them also used that 80A alternator fuse..
I'd suggest trying to find a new one period. They are not easy to find but you can find them new.
