what kind of engine ??
 if 3.8 S/C direct bolt on 130+Amp is from GMC trucks,I did it on my . just change the pulley . forgot what year ,but Alternator rebuilders can tell you all info.

Sorry about that its a LS4 but I made my own alternator bracket so its not the factory configuration. It also is wired to use a 1 wire alternator and not the factory wiring....

I think my alternator went out on my way to my office today. I have had this same 105amp (I think) chrome 1 wire alternator for a long time and used it on a few different cars so its no big deal.

I think I need to up the amps on a new alternator but have no idea how much I need. I currently have 3 electric fans and will have another on the a/c very soon. 2 stereo amps, electric fuel pump, engine/trans mangement, laptop (sometimes), GPS alarm,  and all the other normal electrical stuff.

Should I get something around 110amps, 140amps or more?
Thanks~
