I had a Ford truck do this
very same thing once. It had 2 gauges, fuel and temp. BOTH pegged out at the
same time. There is a small transformer behind the instrument cluster someplace
that knocks battery voltage down to operate the gauges. Mine happened to short
out, sending full voltage to them.

Subject: IML: temperature gauge showing
over heating
Hello List,
I have a problem with my '66
Crown. I was driving one night coming back from a car show when all of a
sudden my temperature gauge went all the way over to right which showed me it
was over heating. I quickly stop the car checking the belt to see if it was
broken. Everything under the hood looked normal so I waited for about a half
hour and starting to drive the car home when it did it again. After getting
home I decided it probably was the thermostat which jammed such, and changed
that first which as many of you know is no picnic if you have AC. After
completing the job the problem was still there. So I decided to change the
water pump since it was original with over 115,000 miles on it. I took the
water pump off, and found nothing wrong with it. As a matter of fact it looked
like brand new inside. I pulled the radiator out and used a hose to put water
in the top of the radiator inlet to see if it would flow out of the bottom
freely, and it did. I'm wondering if it's the temperature sending unit. I
ordered one today from NAPA, and will have it by
Wednesday. If the problem is still there then I'm out of ideas. Does
anybody have any thoughts???
