Hi all,

In december when my Alt went out I took it to a local alternator/starter repair shop and they put a new (aftermarket, not Bosch brand) voltage regulator on it. all is fine.......... New battery about 3 months ago......... Fast forward. Battery light comes on all at once on me. I order a new BOSCH brand voltage regulator from Rusty at *************** because my charging voltage is only about 12 volts............ New regulator on............ Still only developing 12.5 volts maximum traveling down the road. funny thing is, I can draw like 35 amps off of this 55 amp alt at 2400 rpm engine speed and it still runs along at 12.5 volts!

I'd like to upgrade alt size, so I definately want a 65 amp minimum! JC Whitney has remanned Delco gm alternators in 100 amp size for $110 (no core, nada. Bottom dollar price.) These are new remans. ($125 will get it in chrome!

) A new bosch remanned alt in 65 amp size is at least $150. So I am heavily leaning toward going with a gm alt and just making my own bracket.........

My question is, If I get a new 2-wire GM alternator and hook it up, will the charge light on my dash still work? That's the only concern I have.......... my metal-working skills are good enough that I'm not afraid to make my own alt bracket...........

Advice anyone? I'd love to stick with bosch, but unless I can get a 100 amp Bosch for less than $175, I can't justify it..........
