need help with wiring on blower fan
« on: November 05, 2013, 12:56:04 PM »
I'm installing a new blower fan assemble on my wood doctor. I realized both wires from the old and new motors are black. How can I test them with a volt meter to ensure what is hot and ground? I'm not sure how to hook the motor to the power from the boiler.  I need to identify the wires on the motor but they are both black....thanks!

One is hot and the other is not, they can go either way, just like turning over a plug in the wall socket on your electric drill.

I realized one is hot and the other is not. My concern is if they are hooked up wrong....will this damage the motor?..or will it just run in reverse? It's a 115v motor. thanks for the help!

The motor only has two black wires. I'm not sure which one is hot.
