The tachometer in my '64 (300HP 327) has become erratic since I replaced the speedometer. By erratic, I mean that it tracks RPM, but 'searches' and wavers and the needle can drop dramatically under moderate or hard acceleration. It worked just fine until I reinstalled it after reinstalling the instrument panel. I have gone so far as to replace the points, condenser and even the ignition coil. I'm almost out of ideas. Nothing so far helps.
Yes. I disconnected the battery while removing and reinstalling the instrument panel. I suspect either a damaged tach or a voltage problem. I'm wondering now if it could be with the voltage regulator (I'm rabbit hunting, I know) Should I repolarize the voltage regulator? ...or do I need a condenser on the coil ...or a new tach? Anyone have any ideas. Help!!!
