Hi Iceman007

Converting to part wind shouldn't be a problem, you probably know this but what the hell. measure the resistance of the windings and check that 1 set of windings does not read higher than the other set if they do the compressor might be a 60/40 split, if they do read the same its a 50/50 split so it doesn't matter which set of windings activate first. As usual add a timer set to secounds to bring in the secound set of windings after the first has activated.Remove the third spare contactor and you should be ok, unless the secound set of windings try to start in the oposite direction?
Kind regards
