Hello. long story short, my capacitor went out on my ac condencer fan. I replaced the motor and capacitor (with the same spec motor). Turned it on and fan spins wrong way. Am i crazy?
single phase motor
3 uf35 capacitor

thanks in advance. i am at wits end with this ac, heatpump unit.

and i tried the search.

You have the wires mixed up on the capacitor. Carefully follow the wiring diagram on the unit to sort it out. Some fan motors have a plug you can use to change the rotation but it sounds like the wiring is mixed up on yours.

Was it measuring voltage?
Why did it wait so long to blow up (but see below)?
Will this be a warranty repair?

This film is way speeded up; it should have take 1/4 sec. for those test leads to fall back down.
That video is why I hate Fluke. That thing blew on 460v 3~.

Good thing I was wearing protective gear.

The device the meter was connected to was a meter base. All meter bases feed from the top, the load is on the bottom. This one was set up as a test.

Very likely that was 480 volts. 208 or 240 will make a nice POP, but 480 is much more spectacular.

Either way, once you see what can happen, you'll likely check your meter a bit more carefully.
