I just want to add to this thread, I finally got around to repairing my wiring including the Amp gauge wiring. I used the information found in this thread on how to get the 50Amp gauge working on page 15/16 roughly. I used the 18" of fuseable link wire, replaced my fuses and wiring due to corrosion using these clamshell fuse holders Electric Scooter Fuse Holders - ElectricScooterParts.com. Replaced all connection points with new. It now functions as it should.
