Arild makes an excellent point. The reason I am following this thread is that
I also have the problem of "jumping tach", when my 3-stage regulator goes to
float and the alternator output drops to a level where the tach has problems
reading the frequency of the pulses.

My Detroit has a standard 7/8" - 18 threaded tach drive for mechanical tachs,
and next summer I am planning on adding a standard VDO tach sender. These
devices connect to the tach drive shaft and output 16 pulses per revolution.
Note that this is an inline device so you can still connect your mechanical
tach. At $60 seems like a good deal.
