my 88 shiro is running bad. very rich and smoking, cold starts are no fun, etc. i have random lights that come on on the dash. at first they would dim or brighten when i raised engine speed, i replaced the alternator and they went away. last night the lights came back but they blink when i hit a bump or something. then the alternator stopped charging and i had to get someone to bring my blue top to limp her home. here we go... this is the 4th alternator ive put on this car. i dont understand what is killing these alternators.. ive blown 2 sets of headlight bulbs, but not a fuse or fusible link, my air fuel gauge acts very strange, it just blinks and fades in at out.. and when i use my turn signals it blinks as well... it seems like the alternators are over charging , then undercharging, or just dieing all together.
