Folks, Im looking for guidance, I have an industrial diesel space heater, it’s used to warm a large garage. I’m overhauling it having reassembled it after another engineer attempted repair.
I’m puzzled on how the motor for the fan is connected.
It has a capacitor start/run motor. The capacitor is 2 mFD
There are three wires coming out of the motor …brown, blue, and black. The blue being the ‘common’
Resistance measurements are , brown to blue 66 ohms, blue to black 53 ohms.
And brown to black 119 ohms.
Assuming the live line is connected to the blue wire ie, the junction of the two windings. Which wire goes to the neutral direct and which wire goes to the neutral via the capacitor?
Am I correct in thinking the lower resistance winding is the ‘main’ winding, and the higher resistance winding is the ‘start winding via the capacitor?
Any help appreciated
Ps. I don’t know why this strange font , but can’t seem to change it!
As said, you pressed the "I" button before typing. (I corrected that for you.)
