Hi Clemens,
good to hear that the Moggi is up and running again

!
Then I know what I have to do, if my Plus Four pretends to be dead

...
Always have a 13 mm open-end wrench with Jens to disconnect the battery. Just picked one up at the hardware store and put it in my Morgan travel repair kit. You never know 🤗
I will do that Dave. I already called my dealer this morning to see if they have any idea what the problem is and if I can fix it myself. I will also let the dealer know the result.
