Well hello in Australia, that's a long way from here.
Sorry I can't help with your problem.

G'day and welcome. Some tech wizard will be along eventually, sorry I can't help, I'm only at the wiring a plug stage!

Whereabouts in Oz are you from? Toured for two stints of 6 months and a 2 month. Brother and family live in Adelaide.

Welcome, hope you get your wiring sorted. Keep popping back as sometimes it takes a few days for some to start to reply.

Greetings from sunny Wales. Looking forward to the match next Sunday, although with Wales not being at their finest just now, I guess it's probably an Aussie win.

Back on topic, did you mean the DS520-AN? Your pic looks just like the panel on my van (2018). AIUI the AN is the version that CBE supply to van manufacturers. The retail version does not have the big stud marked OUT.

I have looked online for a circuit diagram a number of times but with no success. There are plenty of versions of the user manual available to download though. Might be useful if you don't have any docs at all.

Can you not identify the faulty relay and replace? In the UK we would look on RS Components or Farnell.

Are you sure you're not just reading the back EMF diode?

Can't help but welcome from Bedfordshire.

Indeed.
Have you removed the relay from the board and tested? And what is the actual resistance reading? It would naturally be between 100 and 200 ohms so would probably look like a short on some meters.
