Today I hooked up my test lights. I have 2-lights on each side of the cockpit
hooked up to the wing root connectors. To make this work I purchased 2-more lights
and some new test leads. With the new
test leads I was able to get the connections to work. Once again I have wing tip lighting. It is still not correct but I do have power
at the root connectors.
When I turn on
the NAV/STROBE switch I have the nav lights, strobe lights, cockpit light and
AP disconnect light. When I turn on the NAV switch I have the strobe lights only. No cockpit and no AP Disconnect. When I spoke with Gus last Friday he told me
he would check the Factory Demo RV-12 and see if the cockpit and AP disconnect
lights come on with the NAV switch. He
called me on my way home from the hangar to tell me they did. He also thought there might be a possibility
that there is a problem with the wiring from the control module to the switch
module. The electrical drawings shows
pin 14 (Nav Power) on the control module goes to pin 9 (Nav) on the switch
module. Also, pin 1 (Strobe Power) on
the control module goes to pin 7 (Strobe) on the switch module. I did a continuity test and found them reversed. In reality, pin 14 on the control module goes
to pin 7 on the switch module and pin 1 on the control module goes to pin 9 on
the switch module. I have emailed Gus to
see if he suggests changing the pins. I
don't want to do anything that will cause additional problems. I have also asked if he thinks changing the
pins will remedy the cockpit and AP disconnect light problems. I'll wait for his email before doing anything.
While at the airport I used my newly fabricated prop fixture to
see if the blades are truly 1o off from each other. I clamped the fixture with the electronic
level to one blade. I rotated the prop
and attached the fixture and level to the other blade. The blades are 1o off from being
the same.
