Most Aktiv owners have moved their balmar from its terrible location down in the wheel well. They have moved them farther up where they are better protected from the road elements. With the help of Sam C, Gordon W of Edge Vanworks (who flew to Alaska to help her), and Adam from Nations Starter, the cause of Amber's fire was found to be a white wire which was added from balmar to UHG somewhere during the install at the Hymer factory. Everyone has been advised through the Aktiv FB group to remove this wire. It has almost started fire on some other Aktivs too.
In a normal state of affairs this would have started a recall from Hymer, but with them being gone, it is passing by word of mouth. There are meet-ups around the country every few months where owners share the issues and fix things like this. Sam C has pretty much re-designed the faulty Hymer wiring system and most owners have changed them out. His Suiet Hacks website has step by step videos.
I recommend that all Aktiv owners join that very helpful and proactive Aktiv owners group on FB.
