I haveing a electrical problem with this mr2 na that i just bought. previous owner is one of my good friends but I havent talked to him in a few days to ask him if he has had this problem, but he did mention anything. I bought the car from him on thrusday after work. It started fine then and i took it for a test drive , he drove it to my house, no starting or alt lite problems. The next day after work. I came home, started it a couple times with no problems. Saturday morning, it wouldnt start. just click. Jumped it off, pulled it into the garage to fix another problem, wouldnt start back up at the end of the day. Went and bought a new battery Saturday afternoon, starts right up and the alt gauge is up into the 18v area and the alt lite is on, tach is not working. Check voltage at the battery and its about 18 or so volts. Sunday, I went to start it up and just click. Voltage at the battery was about .49volts. Jumped it off and started right up. No alt lite, no high voltage, battery voltage was about 13 14 volts, Just prefect. Let it run for about 15 minutes and shut it off and restarts no problem. I did a parasitic draw test and between the neg cable and the neg post was 12.2 volts. Pulled all the fuses and the only one that seemed to make a little difference was the alt senseing fuse and the ecu fuse in the frunk. Maybe half a volt. I couldnt get to the big fuses in the same box. The neg cable looked like crap so i put a new one on and didnt help the problem. Tach hasnt worked sense. Any comments? Im leaning towards voltage regulator has an internal short.
