Tractor: MF 275
The fuse in the ignition circuit blows several seconds after starting, probably once the alternator starts charging. (The tractor continues to run). The schematics indicate an excitation diode aligned so as to prevent the alternator charge going back through the ignition circuit: this is missing, which *might* explain why the fuse blows. However, I've had the tractor for 2 years and not seen this. I've disconnected everything else (lights, gauges, etc) and checked for shorts in the remaining cables. Any ideas ???
