I hooked up my FPS today and did the final rigging of the flaps.....but,
when I lower the flaps, once I take my finger off the momentary down switch,
the flaps run slowly for about 2/3 seconds and then the breaker trips. If I
keep my finger on the switch the flaps run faster and the breaker does not
trip. The breaker does not trip when I bring the flaps up.
Anybody have any ideas?

Rene,
Sounds like your wired wrong. I know, no sh*t. The FPS is gounded with the flap motor gets constant power from the buss then switched power from the switch to either up, which will continue to raise until the limit is reached and the motor will stop or down, where the motor will stop at the three predetermined points. Double check to make sure your not feeding constant power into the up or down leads. Isolate each power lead and check for a short to ground, make sure your getting infinity readings on your grounds and not grounding back through the system somewhere which might show up as a high resistance vs. a good ground. Other than that remove the FPS altogther does the flap work OK through the full range? If so it's working OK. Verify the schematic is the correct one, If I recall and don't hold me to it I believe you use the RV-8 wiring diagram from FPS to correctly hook up the module for the RV-10.

What size of breaker do you have? Are you sure it's a good breaker? What
switch are you using? It does sound like either bad wiring or a bad FPS.
The slow running of the flaps tells me that power is being lost somewhere.
In fact, I wonder if somehow, with the switch in the center, the switch is
grounding the positive wire somehow, which is causing it. Do you have a
DPDT switch or a SPDT switch? With the symptoms you describe, I would say
that maybe in the neutral position, one of the polls is somehow shorting to
ground, which would be the poll that is positive when going down, which
would be negative when going up.

Rene, I believe that you may have a defective FPS. some time ago when I
1st installed the system , I went through a test of it, and found that
the leads didn't respond correctly to a continuity check, or operate
correctly when a battery and switch was connected to them. i contacted
the vendor (show planes?) and they were aware of a problem they had with
one of their 'batches' since they distribute them through others they
couldn't notify customers. but after i described the symptoms, they
asked me to return it and they promptly sent out a replacement, which
worked just fine. IIRC the problem was an internally wiring error.
Judging by your builder number its possible you purchased yours from the
same batch I did.

Thanks Deems, Jesse and Rick. When I get back to the hanger tonight I will
do a little more trouble shooting.
I did send Show Planes an e-mail last night explaining my problem, I will
let you know what they say.
Thanks again.

Rick thanks for pointing out the obvious....you were right. Here is the
response I got from Show Planes.
Rene',
Do not use the extra relay deck you have installed, the FPS does not require
that even if you are using a reduced current capacity switch. If the toggle
switch has been replaced make sure it operates in the same fashion as the
original. Also make sure the actuator is completely retracted before making
the required set up adjustment.
Let me know if you need further assistance,
Bryan Milani
Well, my sticks are not wired for a powered switch so I just disconnected
the ground return on the normally closed relays and guess what, the flaps
work. Yea. So for all y'all who have not put in your flap positioning
system, you can not ground the control lines on the FPS. They have to be
powered, one at a time for up and down, or disconnected.
