I have an RV7 with 170hrs. On two or three occasions, I have reached for the flaps and get nothing. I have never been stuck with flaps down needing to lift off so I am grateful for that.
On the first failure read everything and dug in an disassembled the motor, cleaned the grease, and removed an in-line molex disconnect. It worked Months later - the second time I started taking the covers off, rattled the motor lightly by hand, tested again and flaps worked - so I closed up with a declared success.
More moths later - I encountered problem again and embarked on the third attempt to fix this. Once I removed the cover and rattled the motor by hand, it came to life. This leads me to believe that I have a ground problem at the motor.
My wiring consists of hot and ground through the B&C toggle switch. I believe the switch effectively flip flops the wires to result in up or down operation of the motor. Most importantly, I believe that all required grounding is coming through these wires AND NO LOCAL GROUND AT THE MOTOR IS REQUIRED.
Is this correct? or is a local ground to the case on the flap motor required? Because this motor comes to life each time I rattle it, I am thinking that a local ground must be required.
I cannot find anything that specifies that the motor should be grounded locally. However, my diagnostics have led me to believe that each time I put slight pressure on the case, it seems to reestablish its ground.
I am planning to attach a local ground to the motor case. However, I thought I should check in with others to see if I embarking on some voodoo solution.
Thanks,
Dave Smith
