Anyone know how to test a factory 69 tach while it is out of the car. It has the wires coming from the back with the plug however the wires have been striped just short of the plug and another bare wire is spliced into them. Any ideas?

THANKS!!!

Tommy,
There should be continuity (some restistance) between the two wires, if open, tach is bad. From what i found anyway.
