1995 Evinrude 90HP (HE90TLEOR) Tacho problem

[fredricd]

THe Tacho on the motor is intermittant. I suspect that it is a hot fault.
the tacho indicator is OK but the signal from the motor stops and starts.
I have checked the wiring and it appears to be OK. when the signal fails there is no signal on the grey wire on the terminal block on the motor.
Where does the Tacho signal come from and what is its part number?

The powerpack sends the tach signal.

Thank you, but there are 2 models of Power Pack in the Parts List.
The Part Numbers are
0584030 and 0584028.
What is the difference apart from price?
Does it depend on serial number?
if so the serial number of the motor is
G03746072

Yes there are differences, you one you require is the 0584028, the following link should ***ist you. Before ordering some models the tach runs off the voltage reg. Look for a grey wire, would come off either the volt reg or the powerpack. The grey wire should be your tach signal.
