    Hi guys,
    It could be anything from capacitor to the motor itself. I bought it because I love the look of the thing.

    So the motor start going for a bit and then stopped for some reason, don't really know how to use this AM meter, but the terminals on the motor PCB seem to show the voltage gradually getting lower when the motor stopped working again.

    If that means anything to anyone, let me know. Any help would be great.
    Cheers!

    Lubricate the motor bearings first. I use sewing machine oil. Capacitors should not cause this issue.

    Well it was turning when starting moving the motor control PCB around, then stopped.

    If it sounds like an intermittant connection (non mechanical) issue:
    Try resoldering the motor connections, and clean the speed control pot RV601 with deoxit or contact cleaner. Note that if you touch the pot you will need to reset the speed with a 3k test tape. You can verify the pot is at fault by gently tapping on it or shorting it to max speed.

    Wm-3 service manual is almost the same as TPS-L2.
    do a google search and you can find it. I tried to upload it here but its a large file and i guess there is a size limitation on uploading file.
    If you are not able to find it PM me your email address and i will send it to your email as an attachment
