What can I do to examine the cause? Eg I cannot find a fuse to check. I checked the power source. Kind regards, Jeroen This topic was modified 4 months ago by jeroenk.

By the way: I found a fuse right under the power plug (rear 407 air-x). I will check that first. Kind regards, Jeroen – Netherlands.
