Testing a heater motor

[jime]

I've got a couple of Deuce heaters and I want to test the motors before I install.

1. Where to I connect the leads?
2. Will a 12v battery spin the motor for testing purposes?

Thanks!

You should have a pigtail from the motor, which is your (+) connection. Case is ground (-).
12 VDC will work just fine for a lower speed.

Thanks Bjorn. I thought it should work, but with the pos attached to the lead and the neg clamped to the heater frame, I was just getting sparks. Then I realised that I've got the whole set-up on a rubber mat. I ran a ground and they both spun like tops! Thanks for the help! Jim
