my 1jz seems to have killed two (one was the stock, one oem rebuild) alternators in a short amount of time. so here's what happened:
about 3-4 months ago, the "your alt. isn't charging" dash warning lights started coming on (and staying on for progressively longer periods of time) until the alt. stopped doing its job altogether. I quickly replaced the alt. with a reman'd advance auto SC300 alt.
after that, everything seemed fine until about 2 weeks later it randomly started acting like it was losing power (if headlights where on, dash lights would dim/fade), and then the 3 alt. not-not-charging lights would flicker quickly right before it would return to normal operation.
i ignored this because the car was going to be down for some work for 1-2 months. so after I got the car back, it was doing the same weird thing, where the dash illumination lights would fade and would act like the alt wasn't charging, but just for about 30 seconds to a minute i would say.
then two days ago, while driving, the alternator must have just stopped working, because the car would just run off of the battery until it quickly died. it would jumpstart, run fine for 45 seconds, then die. no dash lights, no charging lights, it would just run until it drained the battery after the jump.
so i parked it, and messed with it a few times (jumped it, drove it around), until one last time it was about to die and I had my foot to the floor and it was like a flick of a switch because it came back to life and back to normal....for 2 days and over 100 miles.
Driving home from work last night, it did the same thing, no dash warning lights at all coming on, but the dash illumination lights would just quickly fade and the car would be dieing. Jumped it twice, tried "messing with it" to get it to switch back to normal mode, and then parked it in a neighborhood where it is sitting now.
any ideas of what is actually going on? I have a warranty on the alternator and the day off today, so I will be swapping them but I don't want to have the same problem!!
thanks for reading my long-winded issue
