I have a question about the tach conversion using the 100k potentiometer (pot).
My 1969 car came with the earlier style tach. Apparently this tach is not
suited for the mods as
outlined in the MGB V8 newsletter, and Leon Zaks web site. I scrounged up
another suitable tach
from my stash and made the mods.
When I went to install my newly modified tach I found there is a wiring
difference in the two tachs
and my car doesn't just "plug in" to the new tach.
The old tach electrical connections consist of a:
round female Lucas connector (had a white wire attached that goes to the coil)
round male Lucas connector (had a white wire attached that goes to the ign
switch)
male 1/4" connector (had two green wires attached dunno where they go)
The new tach has a:
round female Lucas connector
a square 1/4" male connector.
male 1/4" connector on the case for ground.
Notice there is one less connector.
Can anyone help me with this dilemma? What wires go where?
