Hello everyone.
Wanted to get a little help for a troubleshooting process, and not sure where to start. I have a MF20 with the Perkins gas engine. The fuel gauge doesn't work, and hasn't since AI bought it.

My understanding is that the resistance change form the sender is what moves the needle, but beyond that I'm a little fuzzy.
