CWorthington Posted April 11, 2013 Report Share Posted April 11, 2013 I installed a older used RF 1 farad capacitor in my 02 passat. About one month later the 90amp alternator when out. I ordered a AutoZone Valeo 120amp reman. It whined when i put it in but i could live with it. About a month later it went bad again. So, i put yet another one in. This one didnt whine however. Today Workshop Alternator came on the dash but went back out. Im almost certain that this one is on its way out too. So my questions are: Can a capacitor over work a alternator if its bad? If not, what could cause my alternators to keep going bad? What is the average price for a HO alternator? Link to comment Share on other sites More sharing options...
Guest DC Power Kyle Posted April 11, 2013 Report Share Posted April 11, 2013 Autozone doesn't make the greatest alternators. On top of it barely being able to keep up with keeping your car charged you have a stereo system. Autozone is all re manufactured Chinese crap. You just have too much demand most likely on your autozone alternator Link to comment Share on other sites More sharing options...
SnowDrifter Posted April 11, 2013 Report Share Posted April 11, 2013 I don't think your capacitor is to blame here.But something really isn't right if you are going through alternators this fast. Can I get a rundown of everything you have in your car?

Nate Futuristic Posted April 11, 2013 Report Share Posted April 11, 2013 a cap if not properly charged will drain your system in most installs caps are useless and only provide SHORT burst of output but then need a recharge which drains your electrical if your alternator cant recharge it as fast as your drawing/draining it then yes it can price of a high output alt depends on vehicle and amps you want id say between 300-400 for a good 200-250a alt ive most likely been ninja'd so fuck it lol down rpping vanderbilt. 30 miles from victoria. i own the 3rd loudest setup here out of 3. but i did put together all 3 setups ^^ Cant wait to swalllow Ghost's babies Link to comment Share on other sites More sharing options...

Wicks Posted April 11, 2013 Report Share Posted April 11, 2013 A capacitor holds so LITTLE energy compared to any battery or alternator there is NO possibility that one could damage any alternator and/or battery. Bad alternators would come from another heavy current draw or faulty alternators from the start.

Guest DC Power Kyle Posted April 11, 2013 Report Share Posted April 11, 2013 VW alternators are more than 200-300 or you're looking in the wrong places. If you want something that will bolt up with no modifications to any brackets or your harness do some research and find the right company for it. You definitely get what you pay for with an alternator. Link to comment Share on other sites More sharing options...

If it's constantly low, it could point to either a bad battery or a discharged battery(parasitic drain). Have you done your big 3?
