I recently installed
Balmar alternators and regulators on my two
Volvo B2003 engines. I noticed I had to run at higher indicated
RPM to get the same speed through the
water.
Pat (Never Monday on this forum) checked
RPM with a strobe and verified that tachometer indicated RPM is about 500 higher than actual.
I have searched threads but cannot find information on adjusting tachs and neither forum or tech data with Balmars addresses the issue.
Anyone know if they can be adjusted without changing pulley size?
