Hi everyone.
The motor control board talked about below is Johnson Fitness JDYF02L RevG. The treadmill is a Horizon T900.
I now have two problems. The second problem was accidentally created while trying to debug the first problem.
The first problem is the incline feature doesn't work on the treadmill. The treadmill was purchased like this in hopes that I could get the incline feature working. The motor for the incline works (it's an AC motor) as I just hot wired the motors connectors from an extension cord *carefully* and i can make the incline go up and down.
The second problem is that now the other motor (the traction drive motor which turns the walking belt) doesn't work either. This problem I DID create accidentally while probing around on the motor control board. I was on the long white connector measuring voltages when the probe slipped and shorted the neighboring pin. Can't remember exactly but I either shorted pins 6/7, 7/8, 8/9, or 9/10. I am calling pin 1 the first pin on the left of the long white connector on bottom in the attached picture. (Thanks to Silmarillion for supplying the picture as I don't have the board on me right now) As soon as I shorted it, the traction motor stopped turning and does not respond to commands from the panel. I would need to confirm but I am pretty sure the relays still click on when the Start button is pressed which gives me hope.
There is a wealth of knowledge regarding these boards here and I am hoping this post finds IamJatinah who appears to have a deep working knowledge of these boards.
Does anyone know how to tag another member or IM them?
If you have any experience with these boards or ideas of what I might have done any comments are appreciated! Please ask questions. I am desperate.
Thanks to all
