i bought my '90 corolla DX about 3 years ago w/130,000 miles on it, now i've got over 205,000... about 2 years ago i had an alternator go bad on me.. i didnt realize i was running off the battery until, yes it died with not even enough power to light up gauges. simple problem, hell alternators don't last forever so i didnt think anything about it. i didnt have any other problems until one really humid hot day this past summer. i was running errands with the AC on the whole time until i had the same problem as before. this time i blamed the heat because i also blew a couple fuses, the AC and oddly, my brake light fuse. this time i had to buy a new battery since it wouldnt hold a charge, i could jumpstart it but as soon as i tried to accelerate it would die. i hadnt replaced this battery since i owned the vehicle so nothing seemed wrong. shortly after having it towed and put through diagnostics, replacing the battery and alternator it would have difficulty starting at random times, one turn.. *click*.. the next it would fire up. its been doing this every few weeks but now seems to be every other day or at least it is more frequent. i'm worried i'm going to have another problem since my lights are dimming at idle and brightening when i rev the engine, but what the hell i just had a new battery and alternator 6 months ago. my experience isnt with imports so i'm thinking maybe i've lost tension in the alternator belt so its not putting out a good charge to the battery. it wouldnt hurt to replace that and maybe i should have put off this post until after doing so w/problem not resolved, but maybe there is something i havent read about yet with these ae92's.. maybe a relay or sensor or something you wouldnt think to check or replace that you all might know about and be able to help me with. any help would be much appreciated. i don't want this charging issue to take away the pride i have in my car and toyota since owning, especially with gas prices and unreliability of american cars. i have many plans for this lil beauty and will post my progress once i get a new rental with a garage so i can do mods this winter. thanks
