I`m having some problems getting my webasto to fire up right.
It only runs fore a couple of minutes don't produce any heat and then switches off.
Have had it at the dealer to check if it needed to be restarted with the Star, but they couldn't figure it out.
Any thoughts on what the problem might be ?

 

update, there is also a lost of power, the STHunit is only getting 4,8 V and the normal value is 11-14V.
Will be going over the ground points and wiring later today.
