many thanks for the very swift reply!
Yes thats what i wodl have thought but the gauge of the wires seemed to militate against that...and with pcb's its a bit hard to trace back.
Also, i am confused by thre being 4 wires if thre is a common chassis return - wouldnt thre be 3 wires only then?
If i power up by trial and error, will i blow something?
thansk again
