Bridgeport Power Feed 6f Motor Mount Question

Also! Do not let both micro-switches turn on at the same time! Bad things will happen! I realize that this kinda event is unlikely. But, a Murphy can happen if not careful. This can even happen with dirty/oily switches that do not make a mechanical contact but rather a resistive contact from dirty switches...Dave

Brand new micro-switches and I tested them with a multi-meter to insure they were set just right without power prior to connecting. So those are in good shape and wiring is right where it should be.

Tested pot it's fine. Now it's back to doing nothing no matter how I wire the pot. It did start once when I turned it on wired the original way...but now nothing. The light is on of course because the fuse isn't blowing. Totally bummed now.

It is easy to happen if one of the switches is wired backwards...
 
You only sent in the board. Other parts of the circuit can be at fault.

What's horrible is that there just isn't much too it after the board. I've got new micro-switches. Which I've taken out and tested to insure they work properly. Then set the switches to not over run each other on the direction handle...neutral and so forth. The fuse holder is new. The light is new. The pot is new. I thoroughly tested the pot today. It works fine. I even tried testing it in the balanced state. About 250 ohms each side. Very Even. The motor is basically brand new inside except for the field windings. But that was done professionally. I don't think that would be wrong. Power switch works or the light wouldn't work. Wiring wise it's all exactly as diagrams show me. Down to the pin on the harness everything connects to.

Tomorrow I'll go over every wire in the harness and check for faults there. Grounded and/or no continuity from ends to pins. :( Beyond that I'm back to it being an expensive mystery. If I can't find it I'll have to call Wayne at icai and ask him what he thinks. Maybe it will be obvious to him.

Know anyone that is great at electronics?

Paul, my thought in my post was not so much about the components, but more about the wiring. Really, it is the composite of all the components and wiring together as a system. I am certainly no electrical or electronic genius. When I tear down electrical wiring, I make a schematic of how it was, and what color wires went to which terminals. I label the connections if they are not already. That way I can put it back the way it was before I started on it. Yes, there may be mistakes, even multiple ones, from the previous owner(s) or builder. The next step is to understand the wiring, what does each wire do, how is it activated or deactivated, and how does everything work together to do what it is supposed to do. Lots of people get overwhelmed by a bunch of different colored wires with no big signs for what each one is and does, seeing the total with glazed eyes. My rule on troubleshooting anything is that I must first understand clearly in my mind exactly how it all works. After that it is a matter of testing things to make sure they are doing what they are supposed to do, and fixing the things that are not correct. We cannot understand why it does not work until we understand how it should work.
