[Tigers] Fuel guage and instrument stabilizer

[genepadgett at comcast.net]

Thank you for correcting both my math and the incorrect reading I said should be obtained. Must be mixing up some other test metrics. Apologies to all for the misleading information. 

You make no mention of my suggestion as to where the regulator might be or how to find it. I take it I must have not been helpful there either? 

I find it curious that you speculate that you may have a broken stabilizer, know that the stabilizer output voltage is supposed to be a constant 10 volts to the gauge and have apparently not bothered to check if it is doing so. The stabilizer output wires obviously run to the gauge and are apparently good since some reading was being obtained. Is that not a valid test?

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....
