[Tigers] Fuel guage and instrument stabilizer

[jim]

I often check gauges with my Smiths instrument tester... I'd never actually
put voltage straight to the gauge...

9 volts is actually 3/4 of 12... but the voltage stabilizer is supposed to
put out 10 volts to the gauge...  I just tried a known good water temp gauge
@ both 9 and 10 volts and it was right on the calibration marks at the top
right of the gauge with either voltage

As I recall, it is bolted (1 bolt through a tab) to one of the lower fore-
to- aft dash brace arms that support the wooden dash. If you still have the
original wiring harness, the light green and green wires from the gas and
temp gauges both go to the stabilizer. So you could just follow the wires
back to the unit. 

By the way, if you put a new 9 volt battery across either gauge, it should
read 2/3 of full scale, since 9 volts is 2/3 of 12 volts. At least a 1 point
check of the gauge to see if it is working properly.

Hello, 

I had a fuel gauge that read pretty well in the top 2/3 of its range, but
then droped like a stone. Tod Brown sent me another one so I could swap it
out. In doing so, I now have lost reading on either fuel gauge as well as
the temperature gauge. Wipers and tack work, so its not the fuse. 

A couple of times during fuel gauge install, and re-install, and
re-re-install, both of the fuel gauges pegged all the way to the right. Not
correct as both had indicated before the dual problems of pegging and
deadness about 4 gallons. 

Maybe I fried the instrument stabilizer? Where the hell is that little
devil? I know its behind the dash but where? WS manual doesn't say; only
says behind the dash. 

How come whenever you try and improve something that is working pretty well,
but not perfectly, you end up making it worse? HEL P! Wires are hanging out
of the dash....
