Stryker help line, how can I assist you.
Jeeze Critter , is everything you use going bad?
Ok you got power in, And I'm sure you checked power out at the leads to the motor.
Did you check where leads(ones going to the motor) are soldered in, at the Rx?
Poor solder joints are a known problem. Also bad connection at the leads themselves.
Unless you figure your time is worthless, and it isn't. Why waste it trying to fix a $27.00 Rx.

Come over to the Stryker forum. If you really have your heart set on trying to fix it, there are several techno geeks availible for you to ask.
Operators are standing by for your questions.
