Hi all,
Some time ago, I installed a redarc towpro into my car. Unfortunately, I haven't had the opportunity to hook the caravan up until recently so did not calibrate the unit.
Today I did hook it up and for some reason the unit will not calibrate. It just keeps flashing blue and green. It also seems it is sending 12v to the caravan, as it immediately locks the brakes when the car brakes are touched. I assume this is because it is yet to be calibrated. I switched the unit to manual mode, but even on 0 setting it was still locking the brakes. I am not sure if I am doing something wrong or if I was unlucky and got a dud unit. I will be ringing Redarc in the morning, but any ideas beforehand would be appreciated.
Scott

Gday
I had the same problem but just did a reset as per the manual and it calibrated immediately. Since then no issues and is working the best of any I have owned.
cheers

Hi Evan,
In the reset, did you just press and hold the control knob with your foot on the brake (I think it said 10 seconds)? If so, I tried this but with not luck.

Hi Scott
yes that is what I did and it worked. Have you contacted the installer about it?

cheers

Thanks for the link Slow one, I have had a read and it seems to be talking about electric over hydraulic. Unfortunately my caravan is just electric. I have tried cutting power to the unit completely but that hasn't work. Will keep trying.

I have just sent Redarc an email (I believe they are off until the 12th, phone went to a message bank), so will wait on a reply. Thanks for your suggestions and I will let you know of the outcome.

It does sound a bit odd. I installed ours recently (Tvan/electric brakes) & whilst calibrating within moments of the wheel lock up the flashing light changed to a ‘solid’ light as per the manual. You didn’t touch the brake pedal during the process before the calibration had had a chance to complete did you? If practical, if I were you, I’d try a reset, & have another go at the calibration.

Being an automatic, I have have to touch the brake to get it into drive, I guess I could try putting the car into gear with the handbrake on then put the trailer plug in, anything is worth a go.
The rest doesn't seem to do anything, as it is still flashing blue and green saying it is out of calibration. I also tried to disconnect the power to the unit but made little difference.

I suspect that is your ‘problem’.

Try:
Drive to long straight quiet road in manual mode, trailer connected.

Stop, in drive, handbrake on.

Set Tow Pro into calibration mode (flashing lights) as per manual.

Take handbrake off & drive off.

Do not touch brakes again until flashing light becomes ‘solid’.

If that doesn’t work I think you have a problem.

Going by reports here and there Scott, you can expect to be well looked after by Redarc (another good South Aussie Company :-)....never heard a negative word about their Tech follow up....quite the opposite.....I queried the tech aspects of one of their products at their front counter a few years ago... the engineer that designed it came out for a chat !

There is an excellent video on the RedArc site that takes you through the whole process. We did not hook up the Ulti for over a week post fitting of our TowPro. All we did was follow the instructions in the handbook and the video and it worked perfectly. All we did was set the controller to calibration and drive down the street for several hundred meters and it was all done

Thanks for your thoughtful ideas on my brake controller. I managed to find the issue in trailer plug socket.
When I wired up the controller, I picked up the blue wire that was run into the rear panel when the towing wiring was done so didn't have any need to look at the plug.
At some time in the cars past (before I purchased it), the trailer brake light wire and electric brake wire were reversed. The result was when the brakes were applied in the car, the trailer electric brakes received 12v, hence locking up the brakes on the caravan.
I really should check the lights when hooking up a trailer as I have been driving around towing for the last 3 or 4 months without any trailer brake lights.
All fixed now and the unit went though its calibration process successfully, and now brakes correctly
Thanks again for everyone's ideas
Scott

A good idea is each morning Check the oil water and tyres and when hooking up get wife to test the lights and brake lights.

hi
On paper the Prodigy controller has more features and easier than yours to setup .
Although it is a difficult choice with Redarc having excellent service and made in ozzy .
Good luck with yours ,hoping u get great service from it .

I am unable to comment on the Tekonsha, but it is hard for me to imagine that it would be possible to find an easier unit to set up than the Tow Pro.
