Thank You for any help in advance:
I have a 1990 Starcraft which I replaced the 40Hp mercury 1990 with a 1993 Mercury 70. The tach is the only problem. No RPM showing.
What I have checked
1)The rectifier was bad so I replaced it
2)The grey wire is intact and picks up the C post on the rectifier.
3) Set tach to 12Pole.
4) Stator has 8 VAC on yellow wires and 12.6-13 VDC running.
5) Stator has .8 ohms on yellow wires
I haven't ordered the Manual for this specific motor, however I do have the manual for my 40hp. It doesn't specify the Tach setting.
The 70 HP mercury is a 3 Cylinder and can't seem to find it on any reference.
I think that about covers it. Thank You again.
