Gaffrig Tach Reads High - 496HO
Last couple times I've had my boat out, my Gaffrig tach has been reading a few thousand rpm high.
Engine is a 496HO.
When I hook up the scan tool, and use the "test tach" function, it commands 3000 rpm, but the tach reads double...6000 rpm.
Anybody seen this before and have an easy fix?
