Re-pinning connectors! The oh so joyous task that is so very tedious, and be assured that it is very likely to be necessary on older machines. To correctly re-pin the connectors you will need a couple of things, mainly a crimping tool, I recommend this one from Amazon for $23. Next thing that you will need is a wire stripper. This is not a necessity but oh so very helpful versus using scissors or a blade. And finally the most important item, the actual pin terminals. I am almost sure that we used Pinside to buy the terminals, but I will update if I am incorrect. On a side note, if available you would want to purchase the next plastic connectors to make it look nice and prevent confusion for later on. And a screwdriver to remove the terminals from the connectors, or a professional terminal remover. Now that we have these items we can begin the work. First decide where you want to begin re-pinning. I had started on the rectifier board.
The first step is two take a photo of the connector to know where the wires go in in case you forget.
Quick note, these are not all the same connectors in the photos, as they were done at different times.
After this you can start on either the left or right side. I chose the right side. I used my screwdriver to remove it.
Then once removed you want to snip the terminal off of it like so.
Then with your snipped wire.
Put it into the wire stripper at whatever level looks/feels correct.
It should look about like this. (sorry about bad focus)
Now take your terminal. looking at it we can see two fins on the right side of it in the photo. The one closest to the left side of the terminal is what the wire should attach too, an the other fin is for the insulation to attach to. Very important.
And place it in the crimping tool like so,
from here squeeze the tool until you hear a click or two.
it should look like this if all went well.
Now insert the stripped wire into the terminal like so,
Pull on the handle of the crimping tool all the way until you feel the pressure release. After that the terminal should pop out of the crimping tool. The wire should not leave the terminal. Now it is as simple as putting it into the correct spot of the plastic connector or wafer, either the old one or the new one. Now repeat this for all the pins on the connector. I don't have a perfect photo of a newly pinned connector, will be added later.
There you go! You completed your first terminal replacement of many to come. As you can see the process is not very complicated, and is quite straight forward the only difficult part is the time it takes.
If anything was unclear or didn't make sense feel free to comment down below I am more than happy to help, or to learn something myself. I can add any suggestions in. Feel free to give feedback as pinball is a learning community. I am not sure what the next blog will be about, I may make a mini post about the play field. Let me know below.
