I looked at higher output alternators for DSMs. If you want to pay $350 you can get a brand new Bosch 160amp for these cars, and there is the larger "canadian spec" 90 amp also, as said above. If i remeber, maybe galants (maybe vr4s) had a larger alternator, I dont know that as a fact.

Galants are 90amps. 1g automatics have higher output alts than the manuals as well.

I just checked napaonline and the NA 2gs have 90 and the turbos have 75. WTF why do they get the 90? Fricken non tubros! :)

I paid close attention to the voltage on my way home from work. Here is how it went:
Started and it was 14.4 at idle.
Started moving and it went up to 15.4
Then back to 14.6 at idle.
cruising at 3000 rpm it was at 15.0ish
after about 2 miles(4 min) the headlights went dim and the voltage dropped to 13.0 while cruising at 3000rpm.
after that idle was about 11-12

So if I purchased a 90 galant auto alternator would it bolt up? I have a 1990 GSX. I also have the alternator relocating kit, if that makes a difference?

Went to uni last night and on the way there the voltage kept dropping. Got down to 8.X volts. So I took the ALT out and brought it to napa and they tested it and it doesnt put out any voltage. A new one is coming on moday!

I was having the same issue too. Drove it around for a year and than the three dash lights came on. Scared the crap out of me so I replaced the alternator. Now I am happy except for the dam squeling I can't get get rid of. I think it is time for a new dampner pulley. Glad you are getting it replaced though.

Replaced it on monday and it charges at a steady 14 Volts. I still need to tighten the belt a little more but all is good. I think driving it around like I was F'd up the battery tho. When I get in the battery is only at like 11.7 Volts.

The battery voltage should be 11.5-12v when when the car isn't running.
