How dO i find out what alt. I have it either 105 or 140. is there a code in the glove box to tell me what it is. If so does anyone have that code to tell me.

Would be nice to know what year, model & engine you're asking about.

Out of my '98 C/K manual:

KG9=140 amp
K60=100 amp
K68=105 amp

The code should be listed in the glove box placard.

Otherwise call a Chevy dealer with your VIN and they will tell you what it came with from the factory.

Sorry to chime in here, but my 1998 K1500, with a 5.7L
does not have any of those 3 codes in the VIN.
Mine is a K19. What alternator is THAT?

If you clean off the alternator the amperage should be etched on the housing...along with some other numbers and such
