check your glovebox for the RPO code below to make sure but mine was a 105A

 

K68 Alternator, 105 AMP.

Thanks, I did check the RPO code and it is the same as yours.  I was just wondering because I have a CB and wanting to replace my linear amp with a bigger one that draws 57 amps max.

No problem.  Only reason I know is because I recently changed my serpetine belt and needed to know what I had to buy the right belt

very.  just not right for my application.  I need the amperage at idle (550-650)  this one likes 750 and up, I also need one that likes to rev over 6000 rpm all the time but this one likes 5800 and lower

Okay, it helps if I read and comprehend as well.  The powermaster 200 should be able to do at least 100amps at idle hot.  I don't have his email or number, there is someone by the name of Dominick that builds quality high amp alternators.  Search for Dominick and alternator in the forums

650 AMPS???

 

You need an AC generator instead.  Then attach your DC converter power supplies to it.
