Every time I step on the brakes, turn my stereo up, kick on the rear defroster...etc, etc, etc....my lights will dim or you can hear my engine running harder


Now I don't know much about cars at all, but I'm guessing that it is the culprit here.

I'm pretty hard on my alternator I'd image, with what I do to my stereo and extra lights everywhere....What would a step up from the stock alternator be? How hard is it to install one?

Thanks

I have the same problem - I read in the faq that a GS alternator might swap in and has more power (90 amps) - i might try it next week. There is also a possibility of using a 110 amp alt from a klze engine - but it might need some extra wiring.

if u have an rs car and want to swap in a bigger alternator have fun especially if you have the dohc engine after swapping to the gs alternator it kept snapping all my belts.

Did you change the alternator pulley while swapping? Because the gs uses a different pulley and you have to get the pulley from the original alternator for the swap.

definetly did but im beginning to think that it also may have done some other damage cause now my car makes a funny grinding kind of noise but its not really grinding and it only does it around 2-3rpm its not really noticable while im driving just when im in neutral revving it a little i think its just a loose bolt or something i really dont recommend this swap or you will have headaches beyond belief i struggled with the issue for 3 months before everything was bakc to normal running status.

Try upgrading your ground points. You can pick up a grounding kit on ebay for like 20 bucks with shipping. I only added 1 ground wire directly to one of the alternator mounting bolts straight to the ground terminal on the battery. Before that my belt would squeal like crazy and break like every 3rd week. One time I broke 2 belts in the same week. Drove me CRAZY. After I added the ground cable I have not broken a belt in 3 years!! I am going to add other grounds also. I understand it will help a lot.
Hope that helps!!

i have the MX-6 V6 alternator in both my MX-3

IN my 92 BP MX-3 i changed the underDP since they use 2 different belts Vbelt and a mico belt flat looking one. use the pulley of a 1.6 sohc and the MX-6 V6 alt. left the pulley that was on the alt. bolted on the alt put belts on wired it up rigged it a little bit runs fine never snap belts sqwels.

On my 93 sohc MX-3 bolted on the MX-6 V6 alt. didn't swap out alt. pulleys rigged up the wiring ran fine never snap any belts no sqwels.

You might also think about getting a capacitor. It may be cheaper than reboulding/buying a new alternator. They vary from $50 to $190 USD, but they're well worth it . It also protects your alternator from crapping out on you when you have things in your car that draw alot of power (i.e. car stereos). It works as a kinda middle-man between your alternator and you lights/other equipment. Instead of hitting your alternator and forcing it to draw power from other items to compensate(like your head lights), it hits the capacitor and draws from IT instead of the alternator . They usually last quite a few years, but when they blow it isn't pretty. You'll probably know before it blows that it WILL blow, so don't worry. I have a pretty heavy system in my car and I'm about to get one from Monster Car Audio for about $90. BTW I have a 92 MX-3.

Thats something I haven't thought about, thanks a lot...I'm going to go check in it.

If you need i have a lightly used Bosch reman. alternator for the sohc that i used for 1 year, that i can sell for 60$ plus shipping.
Let me know.

I just quit my job, so I doin't have much spare money...I'm going to stick with this alternator until it comes inches away from death, then buy a new one

well if you need it its there , its just chilling in a box in my room.

when u switch ur alternator. Make sure u have your battery tested - a dying alternator could have negative affects on a battery, and vice versa
