As I recall, the voltage stabilizer also supplies the voltage for the fuel
gauge in the stock setup, at least on the TR4-A. So if it's the voltage
stabilizer you would also have erratic readings on the fuel gauge. Also, as
I recall, when the voltage stabilizer goes bad, both the temp and fuel gauge
get pegged. Happened to my wife when driving the TR4-A many, many years
ago, so memory may not be correct. I'd have to check an original schematic
and compare to the TR6 schematic.

Subject: [Fot] Faulty Water Temp Gauge?
Hello All:
Need some opinions on what I think might be a problem with my 1969 TR6 water
temp gauge is an electrical unit. Scenario: recently, I've noticed the car
running a bit hot, ie, the needle within an 1/8" of the red zone on the
gauge. I recall at normal operating temp, the needle should be closer to
half way (ambient daytime temps in the 80 - 90 degree range). Once the
needle reaches this "hot" location, it never seems to come back down at all,
regardless of whether I'm at speed or stopped. To me, this is not normal.
What I've done so far: flushed the cooling system, filled with about 35%
anit-freeze, remainder with distilled water; added a few ounces of Water
Wetter; new temp sensor, new thermostat (180 degree), timing checked and
spot on. So far no difference in the way the gauge reacts, indicates the
engine is still running hot so I'm wondering if I might have a gauge going
bad. Anyone have an experience with a faulty water temp gauge? Does it
gradually go bad and give false readings? Thanks.
Gary
