Prodigy Strangeness...

Towed our 2004 Safari 28W to Jackson Center for AC/heat pump and cosmetic issues...

Drove up interstate towards the Jackson Center exit, and had not touched the brakes for quite a while.

About 6 miles from the exit, saw a flash or a blink out of the corner of my eye. Tow vehicle is a 2003 Suburban, with about 5K on it...

Looked out for the blink, and saw it was the Prodigy...it went from .C. (connected) to .NC. (not connected), and back to .C.

It did it a couple of more times, and I kept an eye out on the trailer lights (it was dusk) and saw the lights were steady ON while the controller did this stuff -- knew the connector was probably seated...

Pulled off to the side at the JC exit, and the trailer brakes acted normally. Wiggled the connector, and looked at Prodigy from outside the truck. It blinked .SH. for a while, and then went back to .C. I wiggled the connector again, and it stayed steady .C. Decided to continue on.

On the two-lane to the city limits to JC, the controller went from .C. to .SH. to .OL. to .NC. It spent 98% of its time in .C. mode...

I pulled into the parking lot, and backed it into the area where instructed by Airstream Service. Brakes acted normally.

I got out to survey the parking spot, and then stood outside the truck for a minute, engine running, with door closed. Saw the prodigy (without any vibrations) go from .C. to .NC. and back to .C.

Left a message with the service guy this morning, reminding him (as per instructions) that Safari was out there -- also told him about the brake controller antics...will make sure brakes are checked out...

All the way back, the controller did nothing strange (display was . ., two dots)

I have a back-up brake controller (a activator III that came with the safari)...

Will document solution of the problem here...

While AS is at JC, plan on looking at wiring at the back of the truck and at the Prodigy to make sure all looks well...

What does the back-up brake controller do that the prodigy doesn't?

When backing with my basic/generic digital brake controller I have to turn the gain down to almost 0 (zero) so they won't lock on me.

Sorry, I was not clear...

I only have the Prodigy installed -- the back-up controller is a spare, it is not used while backing up...

I keep the spare controller in the Airstream, just in case...so I have the means to troubleshoot further if Airstream Service does not find anything wrong at the trailer end...

Mine does the same thing

There is another thread somewhere on this Forum talking about this issue. I and another fellow have experienced it. So far no sure explanation has been found.

See this thread.

Here's what I've done so far:

(1) Tekonsha tech support. No knowledge of this issue, no suggestions.
(2) RV dealer. Suggested my umbilical cable was too stiff. Sold me a $40 extension which did not help.
(3) Checked & wiggled all connections on the truck and controller. No link found to intermittent "NC".
(4) Checked with prior owner. He used a different controller and never experienced a problem.
(5) Cleaned connections.
(6) Logged when it happened in hopes of finding a pattern. None noted. Some days it is almost perfect, other days it is very intermittent.
(7) Verified that the brakes in fact DO work when it reports "NC". This led to a theory:

FACT: the Prodigy tests the brake connection every 300? msec by sending a brief voltage pulse. If it detects a failure, it flashes "NC" until it detects a good connection again.
THEORY: The voltage pulse, either due to old wiring, weak connections, or bad karma, occasionally comes through marginally. The connection is actually OK. I verified this by pulling the brake lever on the controller as it was blinking "NC". The brakes worked normally.

Note that the Prodigy will continue to show "NC" or be blank as long as you are braking. This is because it can't test the brakes while you are using them. Once you stop braking, it will begin testing again and verify the connection. So it is easily possible to have "NC" displayed and yet be braking just fine.

The next step is to test the brake wires on the trailer with a meter and see if I can detect a measureable issue.

If anyone else has resolved this issue I'd sure like to hear about it!

...hmmm must be bad Karma...everything in my chain is brand new...

Did yours ever indicate a short or OL?

I think it did that because I disconnected it and reconencted it while system was up, and the truck was running...

It is disconcerning...

You know, at the end of last year, my Prodigy was acting strange too.

When I got to a stoplight, the power output display would be zero when I came to a full stop. Now it tends to go up to about 4.5-5.0 when standing still. Only does it when I've been going a while.

Anyone know if this is normal?

Here's the other thread on this same problem

Hi,

I have the same problem, only different!!! When the controller indicates 'NC' I don't have brakes.

Here's my original thread:

http://www.airforums.com/forum...&threadid=7738

Hope it links!!!

Take care

Mine has never indicated SH or OL. Just the occasional NC.

Hohne, you might check the Tekonsha website, I seem to remember there was a known problem about SH or OL indications... but it was a long time ago that I looked there.

...I am laughing at myself...I kept thinking to myself, I should listen to Roadkingmoe and use the one with the cable attached to the brake...but the prodigy was on sale at Campingworld, so I got that...

Now, how do I explain to Sara that we need a new controller, when I have two in my hand that are less than a month old...



...and an Activator II I used with our pop-up...



I will troubleshoot the truck-end here soon, and post any results...have not heard from AS -- I will call them in a day or two to see what progress they have made on the heat pump/AC and the cosmetic issues -- I will remind them to wring out the brakes...

I had problems with the pop-up brakes that turned out to be a short. The thread is hereabouts somewhere...

Yep. Its a Jordan and that's what I use also. Best controller I have ever owned.

...Sivertwinkie...

On our first trip, the only strange thing that happened is that I pulled into a turn lane for a right turn at about 25 MPH -- the road was rippled up from trucks hitting the brakes hard to make the turn...it was washboarded pretty badly...

I feathered the brakes as we went over the washboard, and the controller misunderstood the operating environment and thought I was stopping at a much quicker rate, and it gave full current to the trailer -- jerked out heads a bit...

Wife thought we had clipped something...I was looking down at the prodigy and saw it was at full-throttle. We nearly stopped completely...it all happened pretty fast...

I have the unit mounted at a 45 degree angle -- I wonder if it was flatter it would have done better...

Everyone repeat after me...listen to Maurice. Listen to Maurice...
