No power to coil

#1

Post by blaineja » 31 May 2017, 18:35

I'm getting no power to my coil. I did run a wire from
Battery direct to the coil and the engine started. I replaced the ignition switch no luck. Not sure if there is a fuse I can check. I'm figuring it's the tach. Is there a easy way to bypass the wiring from tach to wire for now. I do have a good rebuilt tach for replacement but would this solve the problem?

Any help would be appreciated.

There's a two wire plug into and out-of the tach. Take the one plug not attached to the tach housing and jumper the leads. The car should start but the tach won't work.

It's. 69. Do I need to take the dash and gauge cluster off to access the plugs?

Is there any way to easily check to see if the tachometer is the problem before I start taking the dash apart?

Check to see if you are getting power at the coil with the ignition switch in the start (starter cranking) and run positions.

Are you getting power to the coil during cranking? If not, the problem is probably not the tach.
