I got my chipper running again yesterday after I pulled the instrument panel out. Just the simple act of pulling out the panel allowed the thing to start right up, so the problem has to be crossing or grounded wires. I spent a little time straightening out all the wires, taping exposed metal, etc... No problems for now.
My ol' lady went to her mother's house to visit for a few days, so I went and finished a job. It was raining, but I managed to chip two truck loads and finish the job. Sweet, for a rainy day.
