Brings up a good point that some people don't know. When you are picking switches for your plane make sure that you are using switches that are DC rated for the intended current. It is not at all uncommon for a switch to be rated at 10-15 amps AC, but only 3-5 DC or not DC rated at all. Google "difference between ac and dc rated switch" if you want the technical details. Not sure if this was Mark's problem or not, but a good opportunity to hopefully save someone trouble in the future.

The "main" side of the DPDT (double pole double throw) switch was apparently in the process of failing first thing this morning, and by lunchtime it was totally dead...infinite resistance on that pole. This also explains a problem I had a few days ago trying to get the thing started.
