Mark and the List,
I had a "mechanical" temp gauge set-up on my car when I bought it. I pulled
it and replaced it with the original (with parts help from Dick Barker,)
because the mechanical was SO inaccurate....if you can believe it.
Regards,
Allan

Theo:
As you may recall I've had my problems with istrument regulators. I've blown
2 by
following the wiring diagram. So, I bought 2 more and think I may have to
get
somebody else to get it straight. Whach Ya doin' this weekend??? Ha! Ha!
But I'd
like to see a better unit, I may never get my fuel and temp. guage working
again. My
local mechanic suggests a mechanical temp. Too un-original. Thanks Mark F.
