Alternator Upgrade

[scholtmj]

Has anyone upgraded their alternator on a 3rd gen car? When my lights are on and I'm idling at a stop light, the blinkers slow down and that bugs me. I assume all I need is a larger amp alternator - am I right? Has anyone fixed this issue?

V=IR!

do you have a big amp drawing alot of current? if so do you have a capacitor on it? when at idle turn off amp if flashers speeds up you need a bigger altenator.

Yeah what the heck are you running drawing so much power? if its a amp like Larry mentioned get a capacitor I had one with my system and it worked great... If not then yes you need a bigger alternator.

The car is 100% stock. Lights on = slow blinker

wow maybe its a sign of the alternator just starting to go? Is it older or new unit? If so maybe just a stock replacement will do the job.

Your windows must be crazy slow then.

I thought the speed of the blinker was regulated by the blinker module. You could replace that for like $10 and it will change the speed. Good luck and keep us updated on the alternator upgrade. I am looking for some ideas too.

IIRC third gens came with a 105A Alt you can upgrade to a 140 off another car (as long as the plugs match) simply bu swapping the faceplate and possibly pulley

Could be just a bad headlight switch. If your instrument lights & your headlights dim every time your turn signal blinks, then you'd have a charging issue (ie. alternator)
