Bart, I had trouble with one too. I did everything that you said. Plus I took an ohm meter and checked all the wires and locations, it's easy to get one in the wrong place on the voltage reg. Then I even ran it up and flashed the reg. It still didn't work. I gave up for the day and went and had a drink with my buddy that was helping me. the next day I tried flashing it a gain and it worked. sometimes they are just stubburn. The light on the panel might be a kit that skyport used to sell. It lets you know if you left the master switch on. It will go out when the engine is running, and on when the master is on without the engine running. And one more thing, the extra switchs, if they are not in use take them out and the wiring. It's just one more thing to get shorted. Hope this helps. Mark
