Single-speed (before 1977)

Note 1: Up to October 64 the wires going into the fan motor may both have been black. Because of the 2-way bullet connectors these can be connected either way round. With the later fan motor with the differently coloured wires from the motor the fan gives a vastly superior performance one way round compared to the other, try both ways. With the earlier motor it should make no difference.

Note 2: Before 1970 the wire from the switch was Green with a Brown tracer. From 1970 it was Green with a Yellow tracer.
