Trying to power on the electrical system. Got a few surprises.
First, the starter relay diode seemed not wired correctly. When I turn on the master relay, the starter relay is also turned on, and the prop started spinning. That really scared me, but I turned off the master switch quick enough that the prop really just turned about 10 degrees, no damage is done, no one is hurt. But it is scary. Then I measured the diode on the starter relay, it is open from the master relay to the switch connector, which means whenever the master is on, the starter relay is also on. I disconnect the diode and all is fine. I think the instruction coming with the diode is wrong, I need to connect the diode backward from the instruction.
P.S. The starter relay diode should be connected to "ground", not battery positive
