So 42 electronics, 24v converters?

[Xlnt]

Any one knows what these converters are for? They are mounted in my 2006 SO42 next to the battery charger. It is very hard to track the wires since they disappear into cable runners with alot of other cables. Se attachment.

Surely you must have devices that work on 24 volt.
Maybe the diesel cabinheater, my eberspacher (similar to Webasto) is a 24 volt unit and I also use a converter for that.
A simple call to the previous owner (or through the brooker) will give you an answer I guess.
If that is not possible you could switch on all the appliances with a substantial interval and check when the converter warms up .
Or better yet , install an amp meter in the output.
