Hi,
Before I explain my problem, please note that I am not an electronics engineer, but like to tinker - and have a BASIC understading of electronics.
Now onto my problem
I have a Horizon Paragon 2 HRC treadmill with a 013674-DG motor control board. The treadmill lights up as normal, incline function operates fine, BUT belt motor will not start.
I removed the leads to the motor from the control board and connected my multimeter. There is 19v DC at the motor terminals when the treadmill is turned on but not running - when "Start" is pressed on the treadmill, the voltage rises to 20.5V DC. I tested the motor with a 24v DC 15A supply (which I made from an old ATX PC Power supply - thanks instructables.com) and it spins ok, so I'm pretty confident the motor isn't the problem.
I have checked all the diodes in circuit (in situ) and they appear ok (readings one way, open circuit the other - checks one on the diode setting on the multimeter). If I increase the treadmill speed the voltage at the motor terminals doesn't increase (which I presumed it would, to make the motor increase in speed - as the belt motor is rated 180V DC).
Can anyone give me any insight as to what components to check next, or have had a similar problem and found a solution?
I have also noticed, on the board between the two large capacitor are two LED's. The one nearest the motor spade terminals is illuminated (but not at full brightness) when the treadmill is turned on, but not running. When running the LED goes out. The LED nearest the fuse never illuminates.
Thanks for taking the time to read my post
