    I haven’t opened it up yet I have been working on replacing most all the lights, doing a full service, have to pull the blower out and possibly replace the resistor for it also just trying to find what info I can before tearing into the gauges and I appreciate everyone’s input.

    Here are the first,second and third incarnations of the same truck, it didn’t become a dump truck until I believe 2002 then had sat since 2012 until about a year ago. 9B19A010-227E-46BE-8B44-855B90A726B9.png BA00A65A-E295-4B33-AC7F-6D5332D9CAC0.png BC6C750E-ACED-48B6-9C18-FD9B17D52681.jpeg

    Have seen issues with gauges show up when the cab ground connection gets corroded, the one at the bottom front left corner of the cab, has a big cable going to the ground post of the starter. Had one where the cable/wire looked good but was high resistance.
