stock alt. vs. 55amp auto parts store alt.
How much of a difference is there in a stock alt on a Samurai and the 55amp alts sold at most parts houses?
I know that when i run my lights,wipers and heat on high it is pretty rough ...volt meter will drop to right at 12v from 13.8v-14v.....if I use hi-beams it will drop more and lord forbid i have to put my brakes on...brake lights and blinkers drop it too [img]images/graemlins/cussing.gif[/img] I can be sitting at a stop sign and volt is about 11 or less on the meter....this cant be good.

So would I see a big diff going to a 55amp alt? I believe I have read that a stock alt is like 30-35amps...I dont have a winch or a high power stereo system.....I just dont like seeing below 12v on my gauge.
I have considered doing the GM alt swap,but figure in buying a bracket,GM alt,larger wire and fuse plus the time involved I would rather pay the $95 at Advance or Autozone for one that will drop right in.
