[Mgs] The Continuing Quest to Cool my MGA

[Rick Lindsay]

Since the only real indication of over-temp that you
have is the gauge on the dash, I suggest that you may
have an instrumentation error.  BTW, any chance your
FUEL gauge reads too high also?  They opperate from
the same voltage regulator.  If that thing sticks
closed, everything will read too high.
