I have 3 Honeywell actuators on 3-way valves. The Type number is M904F30DS7. These things are ancient and I can't find a wiring diagram. There are instructions on the back of the cover but it doesn't reference terminals, only wire colors and whoever installed these used different colored wires. I'm trying to drive these open, I'm guessing I can just short some of the terminals together but I'm not sure which ones. Anyone familiar with these?
