have a multimeter, you can test to make sure you have DC output from the
controller spades. First make sure you have 120 VAC going in to the controller.
On most controls, you can use a linear taper potentiometer or jump the W and H

voltage. The DC output spades should output DC voltage if the control is good.
can be tested by using a simple DC cordless drill or lantern battery. MAKE
