    What the hell happened to that other board that made cutting it up to fix this one the better option?!

    I was wondering if they'd chewed out the two screws so added the other 4 to try and hold the stack tight?

    That's my theory. That's so much easier than gluing a couple toothpicks in those holes, isn't it?

    This is a working WPC board, but decided to fix this connector hack today. I don't do a lot of board work but I'm good with my Hakko. It looks like this has had extensive "heat wear". Is there anything besides this connector I should take care of while I have it out? Should I be concerned about those exposed traces?

    May be the beer - why the two diodes on the back of the board? I would also be concerned with the burned connector to the left of the connector withe the blue wires. It looks burned. Replace the white connector - not original. Anything associated with J121 needs to be replaced - male and female.

    It is a trick to lift the +5V a bit in order to prevent resets. The execution however will not win a beauty contest.

    The blue wires actually go to the back of J121, the other burnt connector was J120 in line with J121, both the GI. Those are the ones I planned to and replaced yesterday. It's the backside stuff I wasn't sure about.

    The funny thing is, this hack to wire to the back of the board seems totally unnecessary. Why would soldering to the back be done rather than soldering to the pins (not that I'm recommending that, just wondering why one hack is better than the other). An even simpler hack would be to use a combination of the J120 and J121 headers that are the same. J120 was missing the left 2 pins, J121 the right 2 pins.

    I decided the other pins were ok and just replaced the 2. The connectors are all trifurcon'd now. Here are the after pics.

    After all that work why not just replace the whole 120 and 121 header. It still looks hacked up now.

    #1519 2 days ago

    Not a bad hack, heck, it was so neatly executed I don’t know if I’d even call it a hack. But alas there is no thread for well done creative repairs.

    Anyway, I just want to send a thanks out into the universe to whomever did this one. It was very neat, got the job done with parts on hand, no boards were harmed and was very easy to undo.

    I thought about it, but did you see the rest of the board? Ha, seemed like the appropriate fix level. Function over form on this one. But like I said, I don't do much board work, I'll take it under advisement if that's best practice.

    The other thing I was wondering about is the connector. Would IDC be frowned upon for GI? I kind of wish I had one, as crimping each pin was the only thing that made it "all that work", otherwise this would have been fast and easy. I also wondered if I should solder after crimping. This stripper supposedly crimps, but I found it way too fidily and found I could do a nicer job manually. Does this thing actually work for crimping? I need a proper crimper.

    Molex connector and proper crimping tool. One time purchase.

    Once you get a good crimper you will kick yourself for waiting so long.

    #1525 1 day ago

    This is what I use. Its what Bob Roberts used to sell before retirement:

    https://vetco.net/products/molex-crimp-tool-for-062-093-100-156-pins?gclid=CjwKCAiAqIHTBRAVEiwA6TgJw8zeMDVeR7O72Zf4H830ttuBh4e5lYspvBlPLK5sakB65uXdcOXuHBoCzhAQAvD_BwE

    Notice the shape of the crimper in the head. There is a saddle the connector back fits in and the press is curved such that the blades upon criming will fold over and push into the wire.

    This is the cheapest tool I have found to reliably crimp molex pins. If I were doing thousands in a month/year I’d of course look at an official Molex crimper but those are pricey.

    Quoted from Plunger069:

    https://www.greatplainselectronics.com/proddetail.asp?prod=1028-CT
    Here is a great crimping tool.

    That's the one I got. Have literally done a thousand crimps. My crimps look better than factory.

    #1527 1 day ago

    I use an IWISS crimper. It does insulation and wire crimp at the same time, ratchets closed to hold the crimp and does a perfect job every time. Price is right too. GPE is thinking of carrying these. I bought one when he mentioned them. I hope he does start carrying them soon as I'd rather give him the sale.

    I may be in the minority here, but I hate crimped connection. I think it may be my years of working with RC airplanes before I got into pinball, where a crimped connections are not used at all due to reliability issues. To that end, if I do use a crimped connection, I always flow some solder into the joint after I crimp it.

    Regular crimps suck. A proper molex crimp the wire will nearly break before the wire pulls from the pin.

    That one looks nice, I may switch to it for the bench.

    Mine is very similar to this... Has a blue handle, but that may just be a design change over the years... The ratchet motion really helps with the smaller connectors - you can put it in, give it one or two ratchets and it'll help hold the connector steady while you get the wire in. I've used it for all the various Molex pinball sizes with no issue.

    thats the one I use...its so easy and results are great

    Quoted from pinlink:

    What do you guys think about this one?
    https://www.greatplainselectronics.com/proddetail.asp?prod=1026-CT

    Doesn't ratchet and needs to be used twice for each crimp. The IWISS is cheaper

    Mine came with a blue handle too

    Doesn’t look to have the proper shaped crimp head to curl and press in one shot. I think that’s more of a general purpose crimper... it might work but won’t be as easy.

    I’ll second that. I keep checking back to find out if someone has tracked down the smoking hot blonde and.... nothing lol.

    Seriously. I’m buying one of those crimpers. I knownit was all off topic but I was just thinking I needed a new one

    Would these work for crimping 0.156” pins? Been looking for a set.

    Thanks
