[Alpines] fuel sender measurement

[Mary and Ron Tebo]

Bill:

In checking my archive,  I noticed that Julian says that you can check 
your fuel or temp sender by grounding your sender wire, and if the gauge 
goes to top, the sender needs replacement. Also, below is a description 
by Jarrid of what to do if the voltage stabilizer is the problem. Hope 
this helps.

2 ways.

1) Get a voltmeter, and measure the gauge supply terminal voltage
with respect to ground (case wire daisy chain).
Should measure about +10v average V.
If you use an analog meter the reading might be noisy
due to the nature of how the voltage stabilizer works.
A digital meter should read stabile readings.

2) Remove the voltage stabilizer, and connect raw +12v (batt+) voltage
to the gauge supply terminals, and verify if the gauges now read more
or less correctly, they gauges wont be very accurate, but should display
close to real numbers.  If it does, the voltage stabilizer needs replacing.

Some time back I designed a solid state replacement for the mechanical
voltage stabilizer, and Sergio Dimarmo put it in his car.

If Sergio is still lurking...

1) Is it all still working?

2) Why dont you call anymore (we miss you).
