Here it is 1992 Bronco XLT, 5.8L, E40D, 180,000 miles. Everything work
fine except for the fuel gauge. It started moving up and down the scale even
though the tank is full. Settled out at 1/4 of a tank then moves up and down
. Just started after a
heavy rain. (Bad Ground?) Also seems to be affecting the oil pressure gauge
it swung once and then worked fine after shut down and restart. I have a
complete set of wiring diagrams for the truck and there are a lot of grounds
to check.Has anyone ever seen this or has a idea on which grounds to look at
Articles for pre 92 vehicles. E series vans were the last to use the by-metal
gauge, that was until 92, the 92 model year changed to magnetic 12 volt gauges.
F series trucks by model year 87 had magnetic 12 volt gauges. Just because some
web site says it is so, does not mean it is.
