We've got a 1999 Miller Bobcat 225G plus and after using it, it ran out of fuel. So basically I refilled and tried to start it again, it smoked and melted some wires near the ignition switch. The battery cable was a bit tight and I had to twist it to crank. The ignition switch felt stiff between positions, so i was thinking it might be stuck. Im handy but not too great with electrical, should I just replace the switch? Need some advice here
