Goodman air handler blower motor

Hoping to get a little advice.

I replaced the blower motor and wheel on my Goodman 5 ton air handler to get rid of a vibration. The blower motor has 2 brown wires going to the capaciter and a red, black, and purple wire. I marked the red as I did the removal so I know that goes to M1 on the time delay board. I have not been able to figure out the locations for the black and purple. Depending on how I wire it, it either runs continuous or not at all. The air handler is a ARPT049-00C-1A. Thanks.

Black connects to the Com terminal on the time delay board and purple picks up L1 from the transformer high voltage side. (There is a black wire from L1 on this transformer terminal as well)

M1 holds the unused fan speed.

Looks like the fourth digit indicates the metering device on the coil...

I currently have the red to M1 (I would bet a hundred bucks this is right from my previous markings). The black is connected to what I think is the 24v transformer. I think the black connection is marked com, but I will get better reading glasses to verify tomorrow. The purple is connected to one of the two power legs coming in off the fuse panel. There is no com terminal on this time delay board that I can see.

Is your timer a circuit board or does it resemble a heat sequencer.

If you have the circuit board, purple connects to the transformer high voltage Com. Black connects to the circuit board com.

Photo of wiring

The red is going to M1 on the time delay board. The black wire is attached to the transformer below the time delay board, and the purple is attached to the white leg coming off the circuit panel. It runs full time this way.

I have marked the wires

The three motor wires are marked as 1, 2, and 3.

Houston,

Thanks a bunch. You fixed my problem. I moved the purple to the transformer and then I found a hidden lug on the board to plug the black in. Everything works perfect now.
