well? car is a 79. ive seen a couple 83-84-85 tachs that dont work well when cold, this one reads about double what its supposed to. is it something else maybe?
|
Perhaps it's not effectively switching from volts to tach?
|
it could be, now the question is why would it do that?
|
You have an aftermarket to test it with?

bleh, Id say pick up a cheap one from (insert random autoparts store here) and try it out. Then take it back and get a refund once you know the results.

did you pop the hood and make sure it doesn't have a v-8? It happens.

Most autoparts stores here have a return policy on electronic parts. If it's 'installed', you can't return it for a refund.
Do you have a dwell/tach meter handy? Does the car still have points? Or has someone butchered in an FB electronic dizzy? |

Or has someone butchered in an FB electronic dizzy? its still got points, i put the dwell meter on it, and the dwell meter says 800rpms, engine sounds like 800 rpms, tach in the car is at 1600ish, we're thinking a diode or something went bad in the tach. |
