Opening up the Power Pro head

[reible]

When the machine "boots" up it plays a little tune. I'd check to see if that happens, if it does then it is possible that the unit might actually run. So the next step would be to hold on to the motor and push the "ON" button.

A good visual inspection is also in order. Look for nicked wires, look to be sure none of the molex connectors have not seated in the plastic and slide back when then connection is made (not uncommon) and make sure by pulling on each wire that it is still attached to the connector.

From what we have seen at this point both the power supply and control housing are in question so they should both be suspect as is the wiring. I don't see a reason to suspect the motor.

That's not quite right. The warranty terms are stated as:

"5-Year Parts & Labor Warranty - on the Shopsmith PowerPro® motor
2-Year Parts & Labor Warranty - on the standard 1-1/8 HP Mark V motors, all belts, bearings and electronics"

on their page at http://www.shopsmith.com/markvsite/guarantee.htm.

The five years is on the PowerPro motor only--not the PowerPro power supply or the PowerPro electronic control panel.

To the helpful people--and you know who you are--my thanks and I hope you'll post any additional ideas. I've sent the control panel to Dayton. Maybe I should have sent the power supply along with it. I have no way of knowing. Maybe I'll get something helpful back.

To the people who've been having such a good time criticizing what I've been doing--how about being helpful? What am I supposed to do? How am I supposed to get inside the wiring harnesses, the clips, the power supply housing, the control panel, to test? How am I supposed to know what to test and what to test it with? How am I supposed to know what test results to look for? How do I do all that without making matters worse, or getting myself fried with 220v for my pains?

In other words, would you kindly go someplace else? You're not contributing. Shopsmith seems to have no resources to offer. I'm not an electronic engineer or technician. I'm a guy who likes to do woodwork and my unit has been dead since October. I'm doing what I can to figure out a dead unit and to post whatever I can that might help somebody help me, and there's a group of you doing ABSOLUTELY NOTHING that is in any way, shape or form helpful; INSTEAD, you're just puffing yourselves up pointing out how stupid I am. At this point, the very little help I've had from Shopsmith is much more than I'm getting from you.

So would you just go away and let those who are willing to help do what they can? I would greatly appreciate it.

I meant no offense with my comments and I was only trying to help. I did point out that this kind of testing method was limited, but I also offered some analysis based on what you provided. In addition, I agreed with potentially a key finding from your video. I do have considerable expertise with electrical systems. Clearly my expertise is not valued here, so I will go someplace else. Best of luck on fixing your PowerPro.

I will add to what RFguy has already said.

Sometimes one needs a reality check especially when out of one's comfort zone/area of expertise.

In this instance that reality check came in the form of our comments.

I applaud thy attempts although they were less than productive. At least you were giving the problem some serious consideration on your part.

It was obvious to me that you were indeed serious although not well guided. You did very well considering the lack of expertise. Unfortunately those efforts did not lead to meaningful conclusions other than the switch operation(maybe).

So do not be offended as no less was thought of you. You were simply not effective in spite of your good intentions.

So I for one will not go away since doing so will not help you gain better understanding. Keep the faith.

I do not recall you calling any of this to our attention last October. Perhaps we could have guided thee had we been aware of your needs prior to your bread boarding.

None of us here are privey to details regarding how all this works. We can only offer best guesses. Your problem appears to be missing power(not only AC) distribution.

We will all have to wait and see what SS replies.

Thanks JPG. I tried to inject some reality as well. Unfortunately, I think our efforts fell on deaf ears...

I was only a forum member for a short time, but during that time I enjoyed my discussions with many of you (JPG, dusty, reible, algale,...). Again I want to thank the forum and for all of the great discussions and immense knowledge that is collected here on Shopsmith. I don't believe that I criticized the OP of this thread, but rather pointed out the limitations and challenges of his problem. Sadly there isn't much information on the PowerPro because it is a closed proprietary system. Until someone reverse engineers it, that will continue to be a problem. In addition, I am accused of puffing myself up with my posts. Again, I have to disagree. If I had wanted to do so, I would have pointed out that I have an advanced degree in Electrical Engineering and have designed, built and tested systems significantly more advanced than the PowerPro. Since I don't have a PowerPro myself and because no documentation is published on it, all any of us can do is offer speculation based on our own background and skills.

I understand anyone can post anything they want online. I had hoped this forum would have been moderated such that a respectful level of discussion is maintained. The OP has told me to piss off with his last post and I intend to do so, so I will be leaving the forum. Life is short. My health is not 100%, so I choose to only engage with people who are positive. It is not worth my time trying to help someone who is this ungrateful. Again I want to thank the forum and wish everyone the best of luck with their Shopsmiths.

To those who have criticized poihths for his frustrated response, please go back and re-read the thread with particular attention to your own comments.

He very clearly directed his criticism "To the people who've been having such a good time criticizing what I've been doing". If you have put yourself into that category then I would guess that he is talking directly to YOU. You know who you are and what you think.

We offer our assistance, let us assist. Let us not be critical of anyone who comes here for help.

Are there repair facilities for the PowerPro. I think the answer is YES. Check the comments that James (shopsmithrepair.com) and Alex (505smithrepair.com) have made in their web pages. Both state that they can work on a PowerPro. However, they don't boldly claim that they have access to "PowerPro repair parts". Let us hope that they do.

Let us hope that Shopsmith has just failed to declare these and possibly others as authorized repair facilities with access to what might be "proprietary sources".

Dusty,

As always, great post.
