My father has a 20+ year old Hunter ceiling fan that stopped working and purchased new capacitors but he misplaced the hand written wiring diagram. This fan has a 3 speed pull chain switch and a 4 wire capacitor (dual 5 microfarads) with 2 grey wires, 1 brown wire, and 1 green wire. Also, it has a single two wire (5 microfarad) capacitor with a red and white wire. Manufacturer technical service was no help, so trying to put back together. Any help would be appreciated.
