Armitage Scooter rack electrics / external light fault

[da1es]

Hi all, recently picked up a second hand armitage scooter rack, one with an led light board,
All the lights work as they should but the external light fault keeps coming on and indicators flashing at double speed as though a bulb is out,
I have replaced the 13 pin plug as it was a bit rusty inside but made no difference
My 7 pin bike rack works fine without any warnings
Motorhome connection is factory fit Sawiko
Previous owner said he had no fault light, only bleeping when indicting,
Mine isnt bleeping either
Any ideas before i nip to local towbar fitter

The led indicators may not be compatible with the module / flasher unit on your car. Easy to fix I believe with a different unit. A towbar company will advise.

Pal had exactly the same on his caravan.

As said, not all systems like LED bulbs/lights.
