|The tach originally in the car worked when I first got the car, then stopped.
I had a spare tach and swapped it in. Didn't work.
Checked the connections, and I was getting shocked so Obviously it was getting a pulse but, nothing registered.
I took the original one and tried to hook it up externally to as a test. I connected the + to the battery, Ground to the engine, and then from the coil. I was getting a pulse as I was getting shocked while holding the tach, but again, no workie.
Do they fail that readily??
It was either this or a giant box of legos
