I have just bought a 500 Kombi which doesn't run (and hasn't run for 8 years :shock: ), and as I am trying to make it work I am encountering parts which I do not recognize from my experience with my two newer trabis (601). The previous owner seem to have changed the electrical system and ignition system to the electronic version, but this includes a strange little red knob with a few wires attatched to it on the floor of the trabi (Picture: http://i.imgur.com/lSeo5.jpg ). What is this thing, what is it's function (it seems to be rusted stuck if it is some sort of switch) and can it be part of the reason for the car not running? The car is in a different town than me at the moment and i am going there in the weekend to fix it and drive it home. The trabi was parked eight years ago when an idiot apparently drove it very far on the starter engine, breaking something electrical. I went to the car a few weeks ago to try to make it work and have changed the starter motor, so the engine turns over, but there was no ignition. Bringing a new carburettor and ignition system next time, but is there any other possible reasons for the engine not starting? All my manuals are for the 601 and there seems to be little available information on the 500/600 models.
