Tach Problems

["Phillip Erikson" <perikson2@earthlink.net>]

Hi, MG-Listers. After a recent dash R&R on my '66 B, I noticed the tach making
some wild gyrations and then finally quitting. When I took it to a good
electric shop, they said there was no wire hooking it up, so they ran another
wire to the negative terminal of the coil. The tach worked again but it's
reading about 500 rpm lower than it did before the R&R.

Any idea what's wrong?

TIA
