Switched the fridge to 12v with engine running and the wires from the loom to the relay were getting hot.

Took the cover off the relay and it is switching ok, but now I am worried.
I have disconnected the wires for now.
Are there any decent electricians out there who can help....

Checked the wiki without any luck and VW have now discontinued the relay.
