    My electronics skills are very limited so I can't interpret results of the capacitor tests. But from the IGN+ - 7v terminal test, I think the voltage limiter in the fuel gauge has failed. As a final test the gauge can be removed fairly easily and inspected.
    If you want to do so, remove the two screws and surrounding clips to release the clear front cover. Remove the two screws next to the speedo cable and the two E and EGR screws that form line between the speedo and large connector. Pull the speedo and black face out of the white housing. Remove the three hex nuts and one E screw to separate the gauge. Look for burnt or broken parts. I'll post pics of the one I have so we can compare.
