Hi all, first post on here so hope somebody can help. I am looking for a wiring diagram for a Prescold MAKN 100 A2 38 Single Phase Condensing unit. Disconnected the fan motor to isolate potential fault then lost the pice of paper I'd written the connection numbers on!!! Stupid Mistake. Any help would be awesome, Cheers Guys!

Sorry, not familier with the unit but wouldn't the fan feed come from the compressor feed and maybe through a HP switch?
Neutral with all the others. One side of the capacitor to neutral, the other to the start winding.

Cheers,
Andy.

If its only the fan motor you have disconnected then,

Fan live/brown to comp live/red
Fan neutral/blue to comp black/neutral
Fan black to one side of 3uf or 5uf capacitor
Other side of capacitor to neutral

Capacitor size depends on fan motor type, newer ones are generally 5uf
