To All:
I want to Thank everyone for the suggestions
that came my way for the saga of the gas guage
not working, as it turns out it seems to be
a commom problem for me, in a new achronym
COS(Current Owner Supidity), when I rebuilt
my dash and repainted it, I must have put the
mounting bracket for the guage in upside down
as it was shorting out the 2 spade connectors that
attach to the guage itself, thus making the guage
not reading anything.
I took the guage apart in an effort to see if the insides
could be taken apart and that is when I noticed that
the bracket was in backwards.
So I wanted to Thnak everyone who came to my rescue
for all of the suggestions that there might be a ground
problem and in retrospect I guess there was a ground problem
between my brain and the guage bracket.
So Thanks again for all the suggestions.
