Fellow truckers,
Well, I finally conquered my "since I've owned it" non functioning gas
gauge. I had two problems, both to do with grounds. First, the tank sending
unit ground was bad. I used a meter ad found very high resistance. Fixed by
running a separate ground wire from the sender case screw to the frame.
Second, the gauge itself was not grounded to the gauge case. I had called
United Speedo Service and the gentleman on the other end was extremely helpful
and told me this is a common problem. Fixed it by sanding the inner surface
of the case and the rear ground contact of the gauge. When I assembled it, I
made sure the two mounting nuts were good and tight.
I then faced the 12 volt conversion problem. I used a 50 ohm 10 watt wire
wound resistor from Radio Shack ($.99 for two) and now I can tell what's in
the tank. No more guessing or trying to remember mileage.
I used an old article from Classic Auto Restorer as a reference when
checking and fixing mine. I have forwarded the article to Ron for posting on
the Chevy Trucks.Org site. If anyone wants it sooner, just let me know, I'll
e-mail it to you directly.
Happy about the fix.
