What's up Club Lexus? Anyway I drive a 1990 LS400 and I think I have an alternator problem but am not sure. I have a system hooked up to my car (Viper d1200.1 blah, blah) and on Jan. 1, I was riding with the music blasting and my amp went into protect. I said no big deal just overheated, well it didn't come back on and my car started making a noise liking bearings or peices of metal were frying around the fan clutch. I disconnected my power wire and reconnected it and my lights started flashing with no music on. There isn't any noise being made now but everytime I hook the amp back up my lights flash (even with the radio off). I even hooked up a little 200 watt amp and it still flickers.

-My car starts and runs fine
-It doesn't go dead
-I've had my sytem in my car for almost two years and I just started having problems.
-I had my fan clutch replaced thinking it was the problem, nothing changed.

Please help before I toss this car lol.

 

if your alternator was bad internally, your battery light, brake light, coolant light, and oil pressure light would all be on at the same time..

I've hada system in my car for 3 years and have gone through 3 alternators.. i suggest installing a capacitor next time.. but the whole parts flying around under the hood... I don;t know, that sounds bad
