Sorry for the late reply.

So, today i followed your guide and jumped pin 1 (red/Yellow) with pin 1(white/green).


Once jumped i waited for something to happen but nothing happened at all.


I checked the voltage from Pin 1 (Red/Yellow) to ground and i was getting over 12V.


I also checked the current flow once the cable was jumped and it was around 3.6A but no sign of life in the Webasto system.


What else can i check on the unit ?



Thanks
