AS therefore fit some resisters in the circuit to fool the computer. These (I believe are under the back of the van) and they can fail - I had mine replaced after a year of mostly summer driving - I only found out when driving through long tunnels in Austria when an error message said "check parking lights"!

On my Nuevo these Resistors are under the vehicle screwed to the wooden floor not far from the back Axle with no protection from the weather which surprised me when I first saw them. I was going to fashion a protective cover with ventilation but I thought A-S will have thoroughly tested and had this location approved, that was before I realised that very little on the Nuevo is tested or approved.

I quite agree if you are going to use LED lights with the reliability and power saving features then the computer should be programmed to accept the current, then you could use a lighting board that had LED lighting too.

I know those resistors. They are what I would call 'power resistors', high-ish wattage. They must be fitted between the +12v going to the LED and ground.

Hang on a minute, I have filament bulbs. So why have I got resistors?

Anyway I thought the same, they are placed strategically to fail, by being mounted in the salt water spray zone. I plastered mine with Waxoyl.

I've just been out and looked. I have got one 30 ohm I guess 10Watt resistor under the offside rear floor, and two that I have indeed plastered in Waxoyl on the near side. I will instantly rush out and plaster that 30 ohm one with rust at one end, in Waxoyl. And maybe tomorrow I will see if I can waterproof all of them in a plastic box.
All my side / indicator / brake lights are filaments so I guess these resistors must be for the high up 'marker' lights, and perhaps the high level brake light. They are mounted on a plate of aluminium for heat conductance. If I was designing the electrics I wouldn't put them there, I would have thought that any LED lights would have dropper resistors co-located, and in any case reprogram the computer to accept LED currents.
By the way the 30 ohm resistor costs £8.10 from RS components including VAT so I guess that will be £30 plus fitting from A/S who will be getting them from China for 1p each. OK, 3p with VAT and import duty.

Puts thinking cap on and tries to remember Ohms Law from 1967. . . .
if all they are is a dropper directly between +12v going to a bulb and ground, then that's 2.2 amps which in turn is say 25 Watts. That sounds like a lot of power dumping just to satisfy a computer.
Someone tell me where I have gone wrong.
By the way mine is a 2015 Nuevo not a Broadway, so if new models all have LED lights there must be a big bank of power resistors somewhere. Why don't they just pop rivet them to the chassis? That would do away with the metal plates screwed to the wooden floor.

I can't quite work out how you butchered Ohms Law 13.8 Volts 30 Ohms is 0.46 Amps so 6.3W, mind you on the Nuevo you have Stop, Side, Number Plate, Indicators and Reverse as well as High Levels to satisfy so you will be into quite some dissipation in order to satisfy the puter.

It is one big bank.

I must get under and look at my R's I have done enough miles now to see how much crud they get splashed with.

hugegrins scratch head blushes
Nor can I ! I blame it on being old and decrepit.
I think I probably got the wattage of the resistors about right though!
As I say I haven't used Ohm's law for yonks.
My Nuevo has done 8,500 miles ish. I think that one mile is long enough to get them covered in crud but when I got mine it had only done 1,800 miles and was like brand new underneath.
You list the lights I have got which is correct, but on my 2015 model the big lights at the lower back are all filament bulbs - which leads me to wonder exactly what the resistors are for. It's under a cover now which prevents me from looking at the high level lights.

Gi'ss a job, I can do that. think_smiley_46
Presumably that is the job interview for an electician fitter at A/S.
