you're welcomeThanks Mike
Mark- you are correct; the apron lever did not work when I got it (free, he was going to scrap it). The motor would come on with the on/off switch. I spoke with a fellow my wife works with and he suspected the microswitches on the carriage control. I tested them with an ohmmeter and they both functioned properly with the exception that one was oily and indicated 80 ohms of resistance. I replaced them with two of the same p/n (both normally closed) and that made no difference in the operation. The motor appears to be original with Chinses characters on the bottom of the data plate. The aqua button is a jog button and it does connect to 3&4 on the terminal strip.So if I'm following you correctly, the machine is now working as it was when you purchased it, with the jumper installed.
The apron lever never has worked correctly.
What's the story with the forward/reverse microswitches? I see two in the tray and two on the machine
Is the cam mechanism adjusted correctly? (one switch actuated for forward, the other for reverse, neither one for neutral/stop)
On most apron lever machines lever down is normal/forward and lever up is reverse, but it could be configured either way
Is the motor original or a replacement?
What is that aqua-colored button on the gear cover? Jog button? Does that connect to 3 and 4 of the terminal strip?
Sorry I have been away so long. field work, work and life have kept me away from it. New development (and not a helpful one) in that the motor does not engage now with the on/off switch as it did before. Not sure what changed. Power is still getting to that upper left contact via the jumper wire but I do not know how to trace it from there. If you are still willing to help I would appreciate some guidance. Thanks. TimOK Tim, thanks. Do the test I mentioned in post #10 and that should get us closer to the problem
