Mallory box, can't get tach to work!!!!
Ok so I have a Mallory ignition box and an autometer tach. How do I hook this up so it will work.
I have tried:
-Running it like the instructions say, attach the yellow wire to the tach = nothing
-Running a wire to the (-) side of the coil = nothing
-Running a wire to the (+) side of the coil = crazy jumping around of pointer.
Thats all I can think of trying. Can ANYONE PLEASE chime in about how to wire this. I called MSD cuz I thought I needed one of their tach adapters, but the guy there says all it does is "spike" the signal. Thats it. I feel like the problem is greater than that.
Does anyone have this box and an aftermarket tach?
Thanks for the help.
