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?
