Hi Everyone,

I have the above MoHo, and following (I think) a heavier than usual drop off the kerb while reversing off the drive, the camera/monitor is now not working (monitor showing "no input").

Perhaps the cable has come apart somewhere between the camera and the monitor (I'm presuming that there is a join somewhere along the way)?

So...does anyone have any idea where/how the cable might be run between the canera and cab monitor (an "over mirror" type) for an AutoTrail?
I've called AutoTrail, but their workshop teams are out until early September.

Is it possible to get to it by non-specialist people (i.e. me!)?

Alternatively, I saw this kit being sold at the Newbury MoHo show, by DRW Electronics - would it be just as easy to run new cable in, and get a better/twin view set up?

Anyone used this company/this set up, and has anything good or bad to say?

Thanks in advance for any thoughts/input.

Cheers,

Rich.

Have you tried removing the camera and checking for a plug on the rear of the camera or a wiring joint plug close to it ? Also the power for the camera may be picked up from the reversing lights and it may be worth checking these light connections.

Hi GeoffnDee
I pulled the camera off its sticky foam mount yesterday, just to see how it was mounted, but it started to rain so had to abandon any further cable pulling and make watertight again - hopefully will be able to pull some out today, but the hole in the outer skin looked too small for a connector to be pushed through?

I'll take the light cluster out and have a looksee if there's a feed for it - I replaced the cluster with one that had an actual white reversing light (the original was red?!) when I got it, and there were a couple of wires connected, though they were going to pre-installed spade fittings - didn't (from memory) appear to be a "random" extra wire spliced in to anything...
If there was a splice to the reversing light, is it likely that would also power the monitor in the cab, or could that have a separate power source?

I recently changed by read lights over the fixed bed and found all the wiring behind this panel……had to use a mirror and be a contortionist but that’s where I found mine. There’s that many wires that the reverse camera might well be in there and then the cover sits in another cupboard. Mines an AT Dakota 2006.

Dont thin I’d just go for a replacement as there may well be live wires somewhere shorting or causing issues further down the road.

Be prepared as I had to repair another wiring fault for the top near side marker light and the wiring for it had broken in the panel at the near side rear, but boy oh boy, the state of the wiring left in place by AT was terrible to say the least, the workforce should be ashamed of themselves as seen in the other pictures, so little wonder we get electrical issues.

Hope it helps as I’ve stripped out lots to get the pictures for you 👍🏻

MH04RMV they may have picked up power from the reverse switch on the gearbox, but I am not sure about camera wiring, there is some information regarding mirror reversing cameras on the www.sargentltd.co.uk website in the support section that may help with this also there is wiring diagrams for Auto trail models on page 4 of Motorhome technical articles in the Resources section on the top (blue)line of this page. (It does not seem to show camera wiring but may be useful).

Thanks PP Bear & GeoffnDee
Having spent the day crawling under the MoHo tracing wires, removing light clusters/door trims/trunking, and after much muttering of curses and naughty words, I've found the camera wire is run through a couple of rear cupboards, in some trunking next to the bed, out of the garage and underneath the chassis up to the passenger door/dash pillar.

Looks like power is taken from the reversing light (blue crimp on lhs of block, black wire goes to front of MoHo, which converts to the white wires on rhs of block which goes to light clusters)...though there are so many joins (with different coloured wire between each!) in the run, I'm surprised there's not been a fault before now.

I've pulled apart/re-seated the connections I've been able to find, but am still getting "no signal" on the monitor...so I think it'll be a much cleaner job to run in new cabling with a twin camera system...

Thanks for the solar suggestion simbadog - will take a look.

Thanks all.

Cheers,

Rich.

PS
On the plus side, having pulled the passenger side of the cab apart, I discovered a tool pack and (supposedly) 4t bottle jack in a floor recess - who knew!

It breaks me to see such shoddy work and wires exposed to the elements like that, they really should do quality stage inspec at critical points in the build and then a quality final check and not by old Pete, whose been at the firm for 30 years and knows everyone. Give me the job and I’ll turn em around.

Well done on all that hard work and thanks for giving us an update 👍🏻

Ah, sorry PP Bear - I should make it clearer (& be fair to old Pete 😉)...there was insulation tape wrapped around the various joints, I've just had to peel it off to try and trace the various wires though...

Just had another thought, my drop down screen for the reverse camera had a wiring fault in the main cable, which I then had to get repaired, could the issue be there on yours 🤷🏼‍♂️

See this thread, post 2,476

Wow, that's some chewed up wires!

I don't think drop-down screens had been thought of when mine was put together 😁

We had an intermittent fault on our rear view/reversing camera, the . monitor worked fine but the image would disappear. The workshop technician detached the connector at the rear of the camera where it ran just inside the locker and reconnected it which solved the problem for a long time, we'll need to check it again though as it's playing up probably due to the crappy state of some of the roads we've travelled!

Hi Minxy
Yep, once I'd found the first connection from the camera, I dis/reconnected it a few times, alas to no avail.

The other risk area is where it is fed round the dash etc before entering the monitor, the cables could be a bit tight/have acute bends and put pressure on any connections there.
