My volt meter was reading lower than usual and the idle was sometimes surging. Symptoms of a bad alternator I'm​ told.
So my son the Honda mech and new owner of Silverback took the alternator to the shop for a look/see. The tech said the pulley was turning but the alternator was frozen.

I'll report back on the findings, repair parts and labor cost after I get the alternator back and reinstalled.

Cheers,
