76 Johnson 70hp Tach

[knouse94]

Ok, I have replaced the rectifier, all connections are good, have sender hooked to gray wire in harness, tach is set to 12 pole, and the tach zeros when powered but the tach still does not work. Any ideas? Thanks

Check the other end of the gray wire at the motor. It should be connected to one of the yellow wires coming from the stator and going to one side of the rectifier. It doesn't matter which.

Thank you I will look at that.

I don't know what other markings you have on the back of the tach, but on my 12 pole stator I set the tach to 6P (for 6 pulse).

I will check that out. I traced the gray wire and everything is hooked up correctly so that may be the problem. Thanks.
