78 3600 Diesel.
Replaced the instrument panel with an aftermarket. In trying to sort out the panel I did a lot of wiring chasing and repairs. I believe the rear harness is in good shape per the wiring diagrams. Still nothing on the gauges. The panel lights work that are fed from the light switch. I have one wire (original Brown w/Blue)running from the ignition switch to the panel. It has a fuse connector with a 3 amp AGA fuse but keeps blowing the fuse. I have 13.8 volts to the fuse connector and continuity from the opposite connector to the instrument panel. Not sure where the amp draw is, how to measure and fix. The wiring diagram shows a hot running to all three bulbs and the wire to the voltage stabilizer. The panel bulbs worked when I initially hooked everything up. Could I have messed up the connection of the hots or maybe it's an issue with the other wires that feed the bulbs. As I think about it the fuse might have blown when I started the tractor. Appreciate any thoughts.
