Does someone sell the 28 pin harness (or all of them, for that matter) with wires already crimped to it? I would rather solder 28 wires than crimp 28 pins...or would I?

I am resurrecting a Trident project pin that I have had sitting for 6 years. It has been in my family since new; my uncle let it decay in his barn...

Thanks

not that i am aware of .... crimping is my least favorite pin related thing to do, a real pita and i have a decent geared crimper

even with the good crimper i usually add a dab of solder to each pin - nothing is more depressing to have one or two wires come out as you plug it all back together

i get my connectors & pins from both GPE and Bob R
 
With a good crimper, and the wires prepared, it's *much* quicker to crimp them in my experience.

Key is - a good crimper. You should be able to pick up a decent one for under $30.

It's some work, but do it right, and it's good for years...
 
HTR-2262A/3135-CT is the Sargent brand crimper that is made specifically for .100 pins (which I am assuming you are dealing with). Not sure how much crimping is in your future, but spending the $50 to $60 on ebay for a used pair of those is money well spent in my opinion. They make good, strong, professional looking crimps on those little pins. I've fully re-pinned four -35 Bally machines and it made the tedious job much little less tedious (but still not exactly fun).

Thank you for the input. I think I have a tool similar to this one; I will verify. It was given to me in a box of stuff when a friend of mine (engineer at a defunct vending company) gave me a box of fun things.

Funny, I asked a friend of mine the same question (he is not on the forums) and he wondered if the MPU he had in a random FedEx box were mine. Since he has had it for so long, he had forgotten whose it was.

About 4 years ago, I did a rebuild replacing over half of the components. Due to corroded wire harnesses, (hopefully), the MPU was not behaving so he was going to test it in one of his pins. Funny how time just flies.

Another friend has had the head for the last two years. He replicated the cabinet to fix his. Finally, I found the legs, bolts and balls too in my recent garage purge. Its a scavenger hunt!

A couple of years ago I had training in terminating directly from AMP. They explained that soldering in addition to mechanical crimping actually weakens the joint and increases the chances of failure due to movement or vibration.
