I'm looking for a good complete kit that retains the tachometer drive.  My 3000 has the 22 amp 12v generator.  This kit seems complete but no mention of the amps.  Seems to me I've seen 65 and 40 amp kits in the past. I'd prefer 65 amps or better.  This kit says 6v conversion to alternator and skips from 2000 to 4000 and doesn't mention tach drive.  It's lots cheaper though, so maybe there's a reason.  

Anybody know a good source from a reputable company?
