fuel sender or guage

[darren paget]

If someone is able and so inclined, could you do me a favor? For tools
you need an ohmmeter and access to the fuel sender wire on the back of
your dash panel. On the wiring harness on the back of your gauge cluster
there is a grey wire with a black stripe. This is your fuel sender. With
the key off, ground your ohmmeter and put the other wire of your meter
to this wire. It should read somewhere between 0 an 90 ohms, depending
on full your fuel tanks are. The higher the number the fuller your
tanks. After this part is done set the dial on your meter to read volts
for a 12v system. Turn on the ignition key, without starting, and read
the voltage if any on this same wire. Leave the wire connected to the
gauge at all times. If I don't have a problem, hopefully your meter will
read about 4 volts. If it doesn't, I have a problem. All help and
comments great fully appreciated.

I had a problem with faulty fuel level readings. Checked out the sender, etc
down under with my ohm-meter and everything seemed normal. Turned out to be the
connection at the back of the dash gage. Seemed that with years of vibration,
the thin film of copper simply wore away under the head of the fastening nut and
was not making a good connection to the sender wire. I cleaned things up and
found a right sized washer to extend out far enough to contact the un-worn
copper film and all is well again. Don't know if mine was an odd ball situation
or if this is a typically sensitive area. FYI
