I do have 12V DC into the tach. Someone told me that I need to check the signal wire into the tach for AC voltage. It could have up to 90V AC on it. That will confirm if I have signal to drive the tach. And if I do have AC voltage present, the tach is the problem.

Can any of the much more experienced people here confirm this?
