Bailey Unicorn Valencia S3 LED Indicators

Thanks for the reply.
The problem I’m trying to resolve is that the LED indicators don’t give me an audible or visual indication in the car that the caravan indicators are working.

When you say resistor box is this the Ryder one? 
I’ve looked on their website but haven’t found anything obvious for this issue and I’ve also looked at the Sargent Electrical site but it says their units are only for Swift caravans.
I’ve spoken to the dealership but other than agreeing that this is a known issue, have had no other offers of help.

An update on the LED indicator problem..

As I said previously, the dealership from whom I purchased the van are not interested in helping with this and as they aren't particularly local it wouldn't be easy anyway.

I contacted Bailey Technical Support who confirmed that they were aware of the problem and that they used to provide support to remedy it, but no longer. They advised that I contact Ryder and purchase their control unit which, once fitted, would resolve the problem.

I contacted Ryder and subsequently purchased the unit but on receipt I found the installation of it beyond what I would be prepared to attempt.

Far from being "plug and play", according to Ryder the caravan wiring needs to be "spliced" and the appropriate wires fed into the unit together with the supplied resistors and the unit then needs to be fixed to the chassis/body of the van.

I started trying to find someone to carry out the installation for me but with little success. I received an intake of breath from my local Bailey dealer, less than 2 miles away, but in any case they have a wait time of several weeks, if not months before they could fit it in. The person I spoke to said it was actually easier to replace the whole rear bumper with a lighting assembly with filament bulbs!

I have approached a couple of local mobile servicing engineers with a similar response although one of them has taken the unit away to have a look at it to see if it's something he can help with.

I understand that a separate wiring loom can be purchased from Ryder which would make the installation more akin to "plug and play" but that this will limit where the unit can be fixed but having already spent over £100 to purchase the "fix" and that is before I've paid someone to install it, I am reluctant to spend anymore on it.

It strikes me that this issue should have been the subject of a recall of all affected models so that no vans were left with LED bulbs, particularly indicators, but it seems I have missed out on any help that was available and will just have to keep trying. Hopefully, the engineer who is currently looking at the Ryder unit will be able to work it out.

An update on the LED indicator saga on my Unicorn S3.

As previously stated both Bailey and their dealership from who the van was purchased have been no help at all.

I have continued to maintain contact with Ryder who have been helpful but it has been a slow process. 

They originally supplied me with just the bare box and 3 resistors. When I asked them how I should connect the box and fix it in the van they talked about splicing into the van's wiring loom, (beyond me), and sent me a mounting plate FoC. 

When I sent them the photo supplied by Freedom a White Box above they said that this is the unit they used to supply to Bailey but they would send me the wiring looms - if that would help! To be fair to them the looms arrived the next morning - again FoC.

Last evening I met with a local mobile Caravan Service engineer who, although he had no previous experience of these issues had agreed to help resolve my problem.

We followed the Ryder instructions to the letter, or so we thought but having got the resistors and the wiring connected there was no change in that I still had no audible or visual indication in the car that the indicators on the van were working.

After much head scratching and reading and re-reading the diagramatic instructions; in fact it was just an enlarged photo with some lines drawn on it and colour list for the wiring, (which weren't entirely accurate), we started to think that what was described as the Output and the Input connections were actually the wrong way round - either that or we were looking at it upside down! Given that some of the wires were a different colour to what was described in the instructions we thought it was worth a try. Connections disconnected and swapped over and voila! It worked! 

I've since received an email from Bailey Technical who helpfully suggested there was no problem with the caravan but the fault lay with my car ECU! They didn't acknowledge that the issue with the LED's has affected a huge number of vehicles and affected so many customers that they were forced at one time to apply the fix under warranty and then to return to fitting filament lighting to their caravans.

Although not Ryder's problem they have at least stuck with me to help me resolve it - which is more than can be said for Bailey.

I am grateful to everyone who has posted advice on here, particularly Freedom a White Box whose photograph finally made some sense to me and led to the final successful conclusion.

Which is what I wanted...
