Re: tach prblems
maybe the tach is bad and is shorting out the coil

Re: tach prblems

"Unplugging" the tach wire from the "distributor" would indicate to me that he might have an HEI distributor. Are you sure you have the correct wire for the tach feed? Green doesn't sound right to me. I don't have any SW tachs in my vehicles so I'm not 100% sure on that. If the green wire happens to be a ground wire from the tach you could be grounding out the dist. Just a thought... LockDoc

Re: tach prblems
Yep hei . Yeah greens the right wire to go to dist. Have a green which goes to tach side of dist. Red that goes switched ignition in my fuse box. Black that's ground and a white that's for illumination that lights tach when I turn on my lights.

Red to B+ Black to ground White for instrument lighting Green for tach sense. This if for a newer tach and not the vintage model.
