    Default Need Red Parts

    As usual the red forum is no help so I'll try here. Got an old sp-200 wire machine and need a drive motor. Can't see paying $400 for it from red and comp that made motor has folded and I can't find any specs.
    Info I have from motor is

    Jones Instruments
    Stamford Ct
    Motak
    12v
    # P1020-103

    If I could find motor specs I could cross reference and adapt something.
    Lincoln # S16952-1

    Thanks in advance

    Try giving Grainger a call. They can cross reference and match just about any electric motor.
    Chances are that motor is "off the shelf" and wasn't designed and made specifically for Lincoln. Relays, switches and contactors are the same way and have many applications.

    Well $400 is actually a good deal, as my cost is $368

    Before I buy a 400 motor I would prefer a 100 motor and also want to make sure the board that drives it is OK. I'll gamble with 100 but not 400 on a 1980s machine

    The problem usually is with the gear box, not the drive motor.

    In playing with it today I have to wonder if the drive is the problem or a result. Electronics guy helping me out was checking voltage and amp draw and we found there was AC present in the DC motor feed lines. Starting to look like a control board problem. Any other ideas cruiser? There is some wear in the drive gears and if it needs a board also I think it will be time for a replacment machine
    Thanks

    As your electrician will know, that AC your reading is merely a ghost signal. Electricians and electronics don't mix well together

    I can agree with the mixing but would I still see a ghost with the motor out of the equation and using a load to replicate the drive motor? Sad part is the motor and drive seem to run fine when connected up to a separate power supply. Wire feeds smooth and easy with no drag thru the liner.

    questions and more questions but no clear answers

    is the 10 amp fuse on the circuit board blown?

    Do you have arc voltage?

    Is there a timer kit installed?

    Has the 2.5 amp motor circuit breaker tripped?

    If you were to jumper the trigger leads at your machine, does the motor turn?

    Questions that need to be answered....
