Steffen from Norway has just contacted me:
“Hello. Having problems with my aixam Mega truck. Switched to a new battery. Worked as it should, after 10 minutes of driving, the dashboard started joking. The lights faded while driving on the dashboard and eventually all the lights went out. No glow or anything. Smell very scorched and a fuse runs constantly. I have no idea what the fuse is for. All lights work, wiper works. Everything technically works. No life in the dashboard except the handbrake light.
Any tips? Any overview of what the fuse is for? Have never had a problem after I switched to a replacement battery.”
