Sure sounds like it. If you google around there's a site showing how to DIY the IVR in the fuel gauge. What this basically involves is to carefully cut/ remove enough of the guts of the IVR to render it "safe," then wire in an external IVR and run the 5V output to that stud with the black cover which I marked "5V" This will feed 5V then, to all three gauges.

Here we go:

That looks like some delicate work. I'm an Ironworker for pete's sake. LOL
When I did the checks the 5 volt output stud was putting out 12 so do you think that the other 2 gauges got toasted ? How can I check them without 5 volts. If I solder a bunch of brake light bulbs together to cut 12 v down to 5
and use the resistors to check the other 2 gauges do you think that would work ??
