Yup. That was it. Thanks. Pulled the area apart. The bolt holding the ground wasn"t firm. Somehow the nut at the bottom of the hole was semi stripped. Further complication was shown when I pulled and (just for the heck of it) checked the resistance on the scorched bolt with an Ohm meter. Over 2,000,000 ohms. That bolt that glowed orange WAS acting as a resister. [Puzzled as to what happened, as all had worked well on the tractor this spring. Must be like when a circuit breaker suddenly goes bad in a utility room and fire results.] Threw the burnt bolt away. Wire brushed everything clean. Retapped the hole (3/8 x 16 for those curious) installed a new bolt (about .2 ohms this time). Discovered a mouse nest by the gauges (there is a 3/4 inch inspection type hole in the bottom of the switch and gauge box put there for an unknown purpose as it"s position over the main transmission shaft bell housing makes inspection through the hole unlikely). Removed the nest and noticed the insulation on the wire from the generator to the amp meter was observed to be melted free of the wire at the amp meter and down for about 4" (not surprising with enough current flowing to make a 3/8" wide bolt with a 9/16" head glow orange white), so I replaced that wire too. Put it all together (changed the oils and greased all the zerks while I was at it), and it started right up like nothing was ever wrong. Bushogged 6 acres of grass which was level with my eyes while I was seated on the Super C immediatly. Ran out of gas (knew I forgot something). Refilled and did two more acres before the sun set.
