FWIW, my '74 260Z had a short between the negative side of the
coil and the (factory) tach.  Disconnected the tach, no problems

in it in an attempt to rectify the problem but I still had the same
(admittedly intermittent) problem until I stumbled upon the tach wire
short thing.

Good luck with your Z....
