From what I've read it's the tach itself.
What part of Arizona do you live in? I live near Show low. Be nice to have another local teener. |

Could also be the points, condensor, distributor ground, or wiring. But the tach itself is the most likely problem.

Purple/black from tach to 14pin on relay board from memory,don't know if it stays that colour from engine 12pin harness to coil .
Check the connection/condition of the wires at as many points as you can also check you a good earth on the back of the tacho and have full 12volts going to it (red/white wire). Failing that get it repaired or fit good secondhand one, the cost to repair could be up there. |
