hello folks
I have a 1980 tr7 that is just emerging from a 6 year renovation
project I have replaced the factory ignition with a crane xr700
system with the a ballast resistor in line to the coil. prior to this
the tach seemed to work (6 years is a long time though)
the tach is now rarely works. every once in a while it works but most
of the time it does not.
I suspect a ground problem but I am unsure of where the instrument
panel ground is
alternatively I wonder if I should hook the tach wire up before the
ballast resistor but that should not account for the intermittent
operation
lastly can I run a separate wire and somehow wire it into the tach
directly skipping the printed circuit that is on the back of the panel
all together
thanks in advance
Steve
