Hi all, A simple question to you people with AL-KO ATC Trailer Control. When you connect the 13 pin plug into your 13 pin socket ready for towing does the green light flash on & off or does it stay solid !!!
AL-KO ATC Trailer control.

- Start date
It should flash on/off green and then turn solid green. If it flashes on/off green without changing, pull forward a few yards and it should change to solid green and is OK to use.
Remember to release the handbrake before plugging the trailer plug to the car.

Why do you have to release the handbrake before connecting?
I don't release mine sometimes until last thing.

Because it can confuse the self-test done immediately on connecting - with handbrake on, no further movement of the operating cable is possible so the ATC can't check that it'll move.xtrailman said:
Just experience - as I usually use a mover the handbrake is usually off when I connect the 13-pin electrics - but the odd time it wasn't then the ATC couldn't complete it's pre-check until the caravan had been towed forward.xtrailman said:
Mine flashes then goes solid as has already been said.
I too have never heard of the requirement to release the handbrake first so Im looking forward to more comments on this.

Having completed several trips with our New caravan fitted with this system, it dawned on me that I wasn't seeing this light flashing or hearing the "self test" like we did on the hand over.
I thought that it was the car battery that powered this, but have discovered that it only works if the 12 volt power button is on in the van.
Now that I make sure this is on, it all seems fine.
Is this right?

No, it is not right.
The ATC should start up as soon as you connect the caravan to the car via the permanent12v supply from the car.

No.
as you say the ATC is fed from the cars battery via the permanent supply.
Sorry damian I replied to the email alert assuming this was the last post.
John says that his ATC only works if the master switch is on in the van, my master switch is tripped off when ever I get to site, I have mentioned this to my Dealer who informed me that the ATC control unit would not do this, Question to all the electrical Guys any thoughts as to what is causing this.
Reason I am asking this question is , that this is the first van where I have Al-KO ATC fitted, and the first van to have had this occurrence .

With a Bailey the 12 volt master switch is usually left off.
The caravan battery isn't required for ATC to work.

Looking at my Bailey wiring diagram the ATC system is not wired into the Car a van's own 12 v system. It's power in and out is via the 12s plug and socket from the car's 12v supply.
Logically as the ATC is only required when the trailer is being towed, having it powered by the towing vehicle makes perfect sense. It would be quite dangerous for it to rely on the caravans habitation battery, as you would never know if it had discharged whilst towing rendering the ATC inoperable.
