alternator question

[djjdnap 78]

Soo what is a good idle amperage for the alternator to have?

I've been doin alot of searchin and research, but never really found the answer to this question.

I've seen 200a alts that only put out 60-100a at idle.

I've also seen 200a alts that put out 100+ at idle.

what is a good rating?

i know u can get a smaller pulley to make the alt spin faster.\

Just curious because i see a 200a alt i like for 179$ and it does 95a at idle.

thats more than i have now cuz i ony have a 95a alt, lol

P.s.

My transmission went out, secong one in there, plus a new engine.

But the alt on a town car and navigator are the same so no worries

still doesn't answer what a good idle amperage is..

but a good read none the less

The "ideal" amperage output at idle depends upon the vehicle + electrical system load.

Calculate what your amperage needs are, and try and match it up with an alternator that meets (or exceeds) that spec as best you can.
