OK do this....
5 steps to getting an AC 140 amp alternator


1 go to advance
2 tell them you want an AC delco 140 amp alternator
3 tell them you have an SE with the heated windshiled
4 tell them L27 non */C
5 install 140 amp alternator

BTW the way there are 2 L27 and possibly more that have the 140 amp installed on there car............ Including me

Yep my '94 Port has a L27 and it just bolted right up.

Replace the battery and alternator TOGETHER if either are over a year old, or you'll get yourself in the nasty cycle of one or the other every other year.

A weak battery can stress an alternator. A weak alternator can stress a battery.

The first time you replace one and not the other, you risk starting the cycle. Sounds like what happened to you.

i replaced my 105 amp alternator with a 140 amp one almost 9 months ago, its a drop in replacement. It has been working excellently ever since...

I need a new battery tho, cause my alt is working hard to charge it when its really cold out.

yes replace the batt and the alt. they will work better together when they are both new

If you dont change both out at one time, which u should, but if you dont, at least charge the battery you have on there before you install a new alt. that can make a difference sometimes too.
