The battery is 13.8v not 12v, It will drop to 10 ish at start up and rise to 15 ish when being charged.
If 13.8 is ok use rear cig socket if its perm. feed. David.
hi if youve got twin electrics/ battery charger why not take it from the split charger relay, if the boot socket isnt constant live
HI I am a long time caravanner, what is ATC? If you have twin towing sockets the 12s (white) socket should have a permanent live on terminal 4. regards bri
ATC simples All Terrain Caravan...
OR Alko Trailer Control
Can ATC be retrofitted to my caravan?
Yes, ATC is retrofittable to most caravans with AL-KO chassis.
Where does ATC get its power from?
ATC is connected to the caravan distribution box and the supply is provided by the constant live (pin 4) from the grey 12S plug.
How much power does ATC require?
When ATC is activated, it instantly draws 15 amps and must take priority over any other 12 volt equipment using the same pin – I.E. caravan battery charger.
Can ATC also be fitted on caravans with a (7-pin) plug?
Yes. The system requires the use of electrical connections from the 12S(grey) plug. It also works with caravans fitted with the new 13-pin plug.
Where does the LED need to be fitted?
Near the overrun device on the front fairing.
Do the brake lights function when ATC is activated?
No. The ATC brakes the caravan and car softly. The driver will feel when ATC has activated.
Does ATC need maintenance?
No the system is maintenance free.
How do I know that ATC is ready to use?
As soon as the 7-pin plug is connected to the towing vehicle, the ATC completes a pre-flight test. The function status is shown via a green LED on the overrun device.
Green (or flashing green) = ready for use.
Red = ATC not functioning, but car can be driven.
Flashing red = caravan brakes are applied. Car and caravan should not be driven.
How do I recognise that the ATC system is working in the car?
Soft braking is noticed in the car.
It's brakes then.
all it does is apply all caravan brakes so streching the car caravan combi so reducing the snake it has sensors to tell it when the tail starts to try and wag the dog:lolA type of anti lock brakes, but to brake one wheel more to help prevent snaking I think:nenau
It means you can drive faster, and overtake lorries in strong winds, that you wouldn't normally do, because of common sense. I don't think so !!!!!
But in the right hands, it can reduce the chances of snaking.
Learn to load and drive a car/trailer unit properly and you will not need to risk your life on some crap electronics that can fail due to corrosion, condensation, low volts , etc, I make sure my combo is loaded right and can tow at over 70 with no problem at a gross over over 4.2 tonnes, if I start to snake even the slightest I will stop and redistribute the load, no problem, Rick
