I'd guess it's either the switch / connectors to the switch (the internal connectors of the switch are just pushed into the track and peened over, so they come loose and short) or the ballast resistor. I'd try fixing the ballast resistor because I think it's a bit easier to get too (well it is on a 145 anyway!) :rolleyes:

At last i had time too spare! But now I am even more confused. I'am not really an electrician but i found some strange things! I have checked the switch butt that wasn`t it. When i measer the voltage whitout the fan plugged in its about 9volts on the fan connector. The postion on the switch doesn`t matter except on the off postion ;) . When I plug the fan in the voltage is zero :confused: I measerd the fan it self and the omage ws about 2 What can be broken?? The fan is no longer working on non of the speeds!

Put a 12 volt positive and earth to the Fan Motor terminals and see if it runs ...........if not the motor is goosed

If it does spin then check the fuses and also check the voltage resistor for the fan motor

fan motor works and the rheostat also seems to work! Maybe its something before the switch thing cause position no4 never worked! where are the fuses located??
