CBE Distribution Unit DS470-CA in a Carthago

[Pausim]

Isn’t the the fence wire live then?

It is an isolated + output looking for the easiest way back to ground, which might just include induced currents in sensitive components.

Look on the bright side Lenny HB , you have a Guinea pig to practice on, so you will be an expert when you get yours.

I remember my first Scania broke down on the weighbridge, wouldn't start and couldn't get the ignition key out, as I'm removing the steering wheel cover thinking ignition problem try and hot wire it, someone came over pulled a relay and said your alternator has gone. Bob.

As I said Lenny these panels fail all the time with no outside influenc, no reason your friends should be any different.

I'm tending to think of it being more of a coincidence as the panel is out, and when ignition & vehicle lights are on the side marker lights are working and you can hear the relay click in the DS470 and items power up with the SOS fuse in. Maybe just a control panel failure.

Update:
Apluljack don't repair them due to the firmware being Carthago specific & they don't have access to it.
The good news, a new distribution unit is only £270 & the Control Panel £340.

Ta for the update, still a fair hit on the wallet for the replacement. I wonder what software is specific, our C-Tourer looks like it has a standard CBE panel. If I was a cynical old man I would say it is "specific" to make it a dealer (read expensive) part....

Update:
It was just the distribution unit, all up and running, there were a few variations of the unit the one for Jon's van was £310.

I have looked at the old unit not a sign of damage on the PCB at all. So it must have the CPU or another chip that's gone, so does give credit to damage done by the electric fence.
What I don't understand or can see any reason for is why the 7.5 amp pump fuse & the 15 amp media fuse had blown.

Odd one that, and very bad luck.......

Lots of them fail for no other reason than a firmware problem, it’s simple really but both Carthargo and Cbe refuse to accept there is a failure on their side

This is just a guess but once the 10,000V of the fence has got into the electrical system it needs to find a way out to earth and perhaps the pump and media circuits were where it earthed across from. Clearly the milliamperes of the 10,000V is not enough to blow a fuse but perhaps the electrical arc of the high voltage provided an electrical bridge for the 12V to also jump across, taking the fuses out as it did so. As I say it is only a guess but maybe an electrical arc can create a short short circuit allowing other currents to follow.

I came to the conclusion that I had either a power surge through the EHU at home or a lightning strike which did for my system which I seem to remember was what Apuljack had suggested. I have since fitted a mains surge protector on the EHU hookup but it seems that it might have been a surge through the 12 volt system via the vehicle earth or some other access point as seems to have been the case above.

Well so many other owners of Cbe panels have had failures without any reason, we are talking 50 plus, in the UK alone in the last 12 months and all looking for reasons and excuses for crap production skills

Blimey - where do those numbers come from?

Just take a look at The Carthargo forums

Think my PC380-CA has just failed, anyone know what rating the SOS fuse needs to be?

Sadly the CBE manual doesnt say - Not had to use it, but I would start low and work up!

Just noticed your post.
Photo attached of fuse location if still needed, it is number 6 down from the top. I have a Carthago control panel which was bought in Oct 2023. I've listed it in classifieds.
