I do seem to recall an earth connection on the shelf above the heater hose
entry points on the bulkhead
That's where the problem was
What I learned:
all the instrument lights are grounded thru that connection
if the speedometer is not grounded to that connection, thru the harness, via
the black wire under the knurled hold down nut, the voltage stabilizer will
not be grounded and will not function causing erroneous high readings on the
temp and fuel gauges
the speedo and tach are nor sufficiently grounded by their contact with the
metal dashboard (thru the mounting spades) for their instrument lights and the
voltage stabilizer to function, but the hi beam indicator somehow manages to
light up when its not supposed to (high beams not on)
I still don't understand the inappropriate hi beam indicator light - but
I've seen that happen before when the speedo is not grounded.
Special thanks to Marion Carraway who called me on the phone right after my
first post - after we talked he got out a 73 TR6 wiring harness he had laying
around, looked it over and then called me back and told me exactly where to
look.
Thanks to everybody else who responded.
Car is back together now - everything works.
Cheers
Jack Mc
