Zeal 0 Posted February 11, 2008 my alternator's started screaming at me, sounds like it's on the way out. does anyone know if i can uprate my 65amp to a 90amp from a golf gti 16v or passat? Quote Share this post Link to post Share on other sites
steveo29 0 Posted February 11, 2008 yes you can...straight swap Quote Share this post Link to post Share on other sites
Dec 1 Posted February 11, 2008 Yup, these days GSF etc only stock the 90A one as a replacement for the standard 65A one. Every time I've got one...the pulleys have needed to be swapped over though! :roll: Quote Share this post Link to post Share on other sites
waynos 0 Posted February 11, 2008 are you sure its the alternator? mine did this ages ago and it turned out to be the belt worn even though it didnt look it. Try a new belt ,its cheaper than an alternator! if it still squeels then at least you have a new belt to go with the new alternator Quote Share this post Link to post Share on other sites
Zeal 0 Posted February 11, 2008 thanks, might just be the belt, but i wouldn't mind the extra power for my stereo etc.. Quote Share this post Link to post Share on other sites
waynos 0 Posted February 11, 2008 kool, how big is your stereo? ive got an all alpine setup with a 15 inch type r Sub and that never bothered the il 65 amp, a bigger alternator wont give you extra power. Its up to you tho 8) ps if you are looking for power have a look at the optima red / yellow top batteries Quote Share this post Link to post Share on other sites

Its up to you tho 8) ps if you are looking for power have a look at the optima red / yellow top batteries thought it might give a few extra horses :) ive got a sub/amp 16:9/amp nothing too big, but i do a lot of short journeys, so i thought a 90amp alternator might put more power back in the battery, quicker? i'l have a look out for those battery's next time cheers, Quote Share this post Link to post Share on other sites
waynos 0 Posted February 11, 2008 a 90 amp alternator wont charge a battery quicker than a 65 amp one. it will be able to cope with higher current draws (dont think you will be drawing 90 amps even with everything turned on) hope this helps Quote Share this post Link to post Share on other sites
Zeal 0 Posted February 12, 2008 thanks, hopefully just need a new belt then, my friends always advising me to buy stuff i don't need, keep telling him he's just a panel beater. thank god for the Corrado Forum. My alternator only starts to whine when i switch the headlights on, would this mean it's more likely the alternator itself? it's making a few knocking sounds too.

steveo29 0 Posted February 12, 2008 a 90 amp alternator wont charge a battery quicker than a 65 amp one. hope this helps really ? im thinking it does, my battery used to get run down on short trips, after the 90amp was fitted it was better Quote Share this post Link to post Share on other sites
