I just bought a 6245 and can't wait to start using it. I have a few things to fix with the main one being the temperature gauge. The needle jumps when I insert the key but does not rise as the tractor warms up. The fuel gauge also isn't working and it goes all teh way to fuel when the key is inserted. Could this be just a grounding issue? Does anyone know where the grounding wire/strap is located? Also, where is the temperature sensor? Any light anyone can shed on the issue would be greatly apprciated. Fortunately I have a 5211 with all working gauges so I can use those to troubleshoot the issues once I locate them.
