Hi all I've installed Maxilamp 4 LED combination lights on my caravan. The indicators work fine when the ignition is on, but they only light halfway when the engine is running. I've tried a 10 ohm 5 watt resistor on the trailer connector to left and right 12v supply (to earth pin) so as to simulate incandescent globes. I've also tried a capacitor across the indicator supply in case there is an RF signal on the line when engine is running. I don't have an oscilloscope to see what's on the line.
Thanks for your help Tony Ford Everest UA 2018 3.2
