My alternator has failed or is failing. I was planning on grabbing this 100 amp one from Amazon.
http://www.amazon.com/ACDel...&keywords=Alternator
Decent price and I understand AC Delco is a good reliable brand to go with. Their vehicle finder says it is a match for fitting my car (1987 Fiero w/2.5).
But my question is, how does one figure out what the appropriate amperage alternator is necessary for a given vehicle?
I think I read somewhere that you add up all of the values in your fuse box and that should give you a rough estimate. If that is the case, my fuse values all add up to 260! That can't mean I need a 260 amp alternator right?
My car's electrical demands are pretty typical and stock for the most part. The only addition was a 100 watt amp for my stereo added like 8 years ago. And I have the standard Fiero Subwoofer with its stock Fiero sub amp.
I'm on a tight budget for a little while so the $70 price tag on the AC Delco was within reach but I would rather not have any regrets, especially considering the pain it is to swap out my alternator with the engine in the car.
I searched the forums and most of the alternator related posts were pertaining to either the 2.8 or engine swap upgrades.
Thanks for any assistance.

If it is an automatic getting out the old alternator is a pain.
I took a bolt off the dogbone and pushed the engine back a bit to wiggle the alternator under the intake to remove it. Watch out for the cooling line to the intake when taking it out this way.

His car is a 4-cylinder, so changing the alternator will be easy in any case.

That was six years ago! I suspect he's dealt with it.
