Hi Peter,

You're back!! I haven't seen you on here for a while. Good to hear from you.

I built up my loom as I went along so I know I am switching +12v through to the 1st and 2nd speed terminals and the fact that they work independently indicates that I'm not picking up an earth there.

One thing I thought about this morning (and I know it shouldn't make any difference) is that the 12v on pin 4 and the switched 12v to pins 3 or 5 are both from the same fused supply. I'll try using separate supplies and see what happens............................

Nigel
