> Chris, I'm not sure I understand this statement.
My experience with the electric tach conversion in my TR4A is that the tach is
not very happy. I
wasn't able to do careful measurements but the little that I did led me to
believe that the voltage
was likely to drop *below* the critical voltage of whatever regulator is now
inside the tach shell!
In another car, I've had problems with voltage swings and electronics - a rally
computer, something
*made for automotive use* would reset itself mid-event, apparently because of
voltage issues. The
manufacturers realized that this was a problem and sell another box to do
"voltage conditioning" :-)
Dunno. All in all, a mechanical tach might be a better way to go in our old
cars!
