Hymer Duomobile Indicator Woes (1 Viewer)

[Baycott]

We have a similar problem on our LHD 2017 Dynamic Line.

A few weeks ago the left side DRL light and front indicator started being intermittent and have now stopped working.

I spent a whole day swapping over headlamps and ballast units (ballast unit fixings were rusted), headlamp and ballast units appear OK.

So it looks like the problem is on the Fiat side. There aren't any fuses on the indicators on a Fiat they are controlled by an electronic module. I've checked the earth connections.

I have been thinking it could be a relay supplying power as both the DRL and Indicators are not working. I can't find any info of the relays and I've found it impossible to unplug relays in the under bonnet fuse box.

I will have a look at info SandraL mentions.

After reading most of this thread in conjunction with the HOG groups postings I have fixed (albeit temporarily) my non working front LED indicators and DRLs.
The very thin wires in the loom were badly oxidised and broken where the overly tight cable ties hold the loom in place.
IMO the ties crack the insulation, allowing air and damp in. The wires in my loom were broken at 2 out of the 3 cable tie points.

The only cable ties that hold my loom in place were on the back of the lamp unit and one that held it loosely to the chassis. None of the breaks were near where the ties were. I still reckon the wires have been nicked by the stripping & cutting machine.

Just been out to my van and found the other headlight DRL/indicator not working looks like it’s developed the faulty wires as on the drivers side so a bit of soldering to be done, just turned three years old so lasted a bit longer than less than one year

Found the cause of failure as Lenny HB, I found three places one looks like Lenny said wire cutter the other two were where the cable was clipped behind headlight and had been doubled up to fit behind it
really annoying that Hymer have not recalled or sent replacement looms at no cost

Nearside wiring loom failed yesterday luckily I had a spare as prepping van for Spain. Repaired old loom only one wire insulation damaged in two places less than two inches apart hidden under protective sleeving usual looking like a Nick/cut in the insulation corrosion attack on copper strands causing continuity failure. The nicks were between two of the very tightly fitted cable ties holding the securing clips. 2 inch section cropped out and new length inserted soldered and heat shrinked. Thank gawd it happened this weekend and not next when we head South for the ferry to Spain. The cropped out section is very pliable and despite a lot of bending the insulation shows no sign of cracking. Under high mag inspection there is the faintest pattern visible on the insulation either side of the nicks/cuts suggesting it’s was clamped during manufacture and probably nicked/cut at same time during the manufacturing stage. The cuts were hidden under the heavy sleeving reinforcing this assumption. Continuity test of all wires on completion of repair indicates all good so at least I have a spare. Hymer/Hella need to get a grip and own up to this obvious fault.

No idea why the photos are duplicated

I have an Olde B634 and have been dreaming of owning a van like yours.
I parked up next door to one 4 weeks ago while in Vera….2015 model which the Frenchys have owned since New.
They invited us in for a wee look … and they had Nothing positive to say of Hymer Quality!!!that we should stick with our Olde 2006 model.

When I repaired my looms I took both looms out and throughly inspected them and made I think it was 7 repairs (detailed further back in the thread).
I said at the time it looked to me they had been nicked in the cutting/stripping machine. The insulation on thin walled auto cable is very stiff and if it gets a slight nick it will crack/split when bent.

I now carry a gas soldering iron & sleeving.

 

[Stewart J]

Also carry an electric and a gas soldering iron Lenny so much for Hymer quality

Looms are made by Hella.

On my third Hymer I doubt if the next van will be a Hymer. They are OK for a mid price van, problem is they have been hyped up in the UK as a quality van which they are not.

 

[Stewart J]

Looms might be made by Hella Lenny but Hymer will have quality control systems in place and they know there is an issue but turning their backs on both it and their customers. Also Travelworld who are the only supplier of replacement looms, do not keep them in stock despite the number of orders they have had for them and the price has now increased and almost doubled from £65 plus carriage to over £100, that’s taking advantage in my books.

That's taking the pee they were originally £50.

I paid Reliance at Chichester in Sept 21 £38.64 x2 + carriage and Vat = £98.38 for two looms as I was having to keep taking them out and repairing new faults on existing ones I gave up as I lost the will

That’s good to know originally as said in my thread only TW supplied them.

Chris is very good always was at Premier MHs

The guys at Reliance came from a Hymer dealer although they are not officially anything to do with Hymer they have good contacts and will get parts for you.

Do they not get all their spares from TW ?

 

[Lenny HB]

Fairly certain they get them from Hymer Germany direct.

I agree with Lenny HB they sourced from Germany and the posted on to me

I was told some time ago that Hymer Group had centralised all their parts under the control and management of N+B

Some macro shots of one of the breaks, I am leaning towards Lenny’s idea they have been nicked during the manufacturing process which has allowed moisture to access the copper core. These breaks were hidden by the heavy woven protective sleeve so there is no way they could have been damaged in situ. The wire is still very pliable and bending it through 180 degrees did no damage to the insulation.

Have a look at the photos in my post #46 the cuts on my loom were completely circular and clean.
To me it looks like on the wire cutting and stripping machine the stripping blade has come in out of sequence as the cable is threaded through.

It does seem odd that vehicles over several years have been affected, unless a large batch of looms was made and put into stock.

 

[Stewart J]

I have looked at them several times over the months Lenny and my engineers head totally agrees with your theory. Have seen reports of newer vehicles having same issues.
When you off wandering again. 3rd March for us Santander then South to El Rocio to access the Donana national park, onwards hopefully to Tarifa for a month to witness the stork and raptor migration for all of April.

Original plan was to go mid Feb but 'er indoors wasn't keen so now we can't go util the beginning of April as I'm not allowed to go until after grandsons birthday.
No plans will just head south.

We would normally be down there at this time I’m very envious we have had to delay any trips for personal reasons at the moment but we will get back down there soon.
Do you go over to La Janda there’s usually great birding there lots of Cranes and the occasional Sociable Lapwing ,Spotted Eagles & several different Harriers and many more also Bald Ibis at salinas at Barbate and Vultures at Bolonia one of my favourite places some great views from there.
Have a great time
I agree with you about wiring looms mine were exactly the same there should have been a recallbut that aint gonna happen

It will be our first visit in a motorhome, we have holidayed in Tarifa staying at a hostal for a month at a time a total of 6 times over the years both in spring and autumn. The spring is special because it’s so green and of course the truly speculative shows of wild flowers which give the region its name “land of the painted fields” we have visited all the sites you mentioned on many occasions.

Yo Alan you were lucky I have just received this Reliance price has rocketed

Took the repaired harness and the cropped out failed piece of wire to a very experienced auto electrician friend to ask for his thoughts. Manufacturing fault during the clamping process resulting in damage to the thin walled insulation allowing moisture ingress was his conclusion. He also thought the cable ties were far to tight and could also cause a problem.

Same as my conclusion.

Blimey that’s over double glad I bought mine when I did are they ever worth that?
