Found an online source for a two groove idler pulley. $556. Not going this route
Found a serpentine belt conversion online for $409 that looks like it may work
. Will dive on engine
tomorrow to see about getting that to fit. Will buy the Balmar
if it will (from MaineSail of course) and keep the Amptech regulator
as a backup. I will then have two regs and two alternators.
Will be nice to rid the engine
space of the dreaded black dust.
Thanks for the guidance.
