Recently, I have had problems where the alternator on my 97 GST fries up. I have owned the car for a month, and have gone through the stock, and 2 aftermarket alternators. The problem started when my battery died a few weeks back, where I left the radio on while cleaning it. We got a new battery, and also tested the voltage on the alternator, which was low. I proceeded to get a new alternator, and 2 days later, I got stranded on the side of the road after the car suddenly died. I figured that the alternator I got was fraud, so I got a new one and put it on. The car sat at the shop with the new one on for about a day, and when we started the car up, the idle was bouncing up and down. The tune had been erased since the battery was disconnected. So, we reset the tune and checked the voltage on the alternator which was 14.2v. I drove the car around the block to make sure everything was running fine. The car seemed to be running ok and I pulled it back into the garage. Once in the garage, I could smell something electric burning from under the hood. The alternator was tested again, and it tested at 13v. Just from driving the car for 2 minutes, the alternator was fried. Both the alternators we bought were aftermarket remanufactured models. We are trying an OEM remanufactured Mitsubishi alternator to see if anything changes. We checked if anything leaked on the alternator, and it was completely dry. The A/C and the radio was also off while I drove the car around the neighborhood. The oil pressure, and temp. of the car were both normal. The car is also heavily modded, and I'm not sure if any of the mods could influence the alternator frying. Here is everything done to the car:
Evo III 16g (ported) Turbo
Ported exhaust Manifold
Ported O2 housing
FIC 1000cc injectors
Headstuds
K&N Filter
Apexi N1 Exhaust
Dejon intake
RRE downpipe w/ test pipe
Symborski shifter kit
Autometer gauges: Boost, EGT, Oil Pressure
Dejon Upper Intercooler Pipe
HKS ssqv Blow off valve
Dejon Front Mount Intercooler
Hallman Pro Manuel Boost Controller
Walbro 190 fuel pump (re-wired)
SS fuel line w/ Summit filter
Fuel Pressure Regulator
Visteon Radiator
DSM Link
AEM UEGO wideband
Fidanza 4.3 clutch
Fidanza flywheel
SS clutch line (Redline tranny MT-90 fluid)
Tociko Illumina Series Struts
Eibach Pro Kit
Baer Big Brake Kit
Racing Seneka Typhoon 17x8 wheels
Roll cage
Five Point Harnesses
RRE strut bar
I'm afraid of putting the third one on because I'm not sure if that one will also fry. If you have had any similar problems or have any suggestions please let me know.
