[C320-list] Club Racing the C320

[brucestanley]

Hi Chris
as I recall, the back of the Tach has 2 or 3 settings. When I first 
installed the 80Amp Alt my RPMs went well beyond my Yamar 3YM30 3600rpms.
So I altered this tack setting and bingo, the RPMS were back to the expected 
normal ranges.

Hope this helps
