Title: How do I decipher how much Amps an alt is?
Post by: 8v-of-fury on November 22, 2009, 06:10:35 pm

When i purchased my 91 parts car it came with the alternator that was on the engine (65 amp i presume) and one that came with.. now i am unsure if it is also a 65.. 75.. or a 90? (these are all the ones ive heard floating around).

How can I tell what's what :) ?

Also! instead of starting another three line thread lol.. Do 81's come with a oil baffle under the Valve Cover? My 91 has one.. but i haven't taken the VC off the 81 yet.. and want to know if i should throw it in on the next order.

no clue on the alt.s

From the factory I haven't seen an 81 with a cover...take the oil cap off and look ;)

maybe a little off topic...

Lucas, I never thought of taking the cap off :( I'm using inappropriate language again - modified by burn_your_money ! found out 81 didn't come with anyway.. gonna steal the one off the 91. found out this thing has 725k kms not the 408k i thought before!

yes your slaughtered cow head is a little off topic.. but sometimes you just have too....

IF there is still a sticker left on the casing it'll usually be on there, or stamped into the casing somewhere, usually around the sides..

Look at the alternator connector. IIRC the 90 amp ones have a more heavy duty stud, nut and eye terminal type connection while the lower amp ones have spade connectors that push on. I think all of them are otherwise pretty similar. Also, IIRC the 90 amp alternators came with air conditioned mk2 cars, without a/c you get the lower ampere unit.
