No hard but if the connectors are fried you should also replace the pins on the board....also not hard but harder

Ed has parts and tools.

For the board learn soldering, and check through and across board continuity from the pins onto the board away from the area you worked to check your work before putting back in game.

For wires - snip off bad part, strip a little casing, squeeze on a new pin - stuff it into connector. Get a lot of extra pins ( they are cheap ) and practice at a table or work bench before doing it in a game where you might be working at funny angles.

A little practice and you'll find it fast and easy.

I would definitely re-pin the connectors. I got one of the boards from Echo Lake for my Foxy Lady cocktail, and still had problems with some of the switches not being recognized. I re-pinned the connectors for that and problem was fixed.

Also, had the same issue on my Attila The Hun. Re-pinning fixed it.

Really, for any 30+ year old pinball, you should re-pin all connectors. Taking the time to do so now will save you a lot of head scratching and troubleshooting issues in the future!

A good crimper. Doesn't have to be the most expensive, but get a good one. Wire cutter and wire stripper unless you can do a good job with a cutter.

If you are talking for the board, learn/practice desoldering and soldering on a scrap board first. Then soldering iron and what ever your budget allows to remove solder. Solder braid, solder sucker, Hakko 808, etc.

Not as hard as you think. I just did my first ones not too long ago. you can get all the supplies from Great plains as reccomended above, they ship fast and also refund any shipping charges that were below the actual ship cost, top notch. They also sell a great crimping tool for about 30$ I believe, just get the cheap one they have it works great unless you plan to do a HUGE amount.

+1 on that as well, I did that too.

Replacing the male pins on the board is easy but one thing to do before putting it back in the machine and getting mad it does not work is to check the pin connections BEFORE taking it off the bench.

If the pin holes are "thru plated holes" or have a trace on both sides with the male pin in connection make sure when you solder your new male pin in place you still have that connection. Test with your multi meter before and after if you are not sure.

Crimping new pins is simple, if you have a decent crimper and stripper handy.

Best tool ever. Get one

With the right tools and a little practice, easy.
You can do it!

Do you have othe games to compare them too?

The larger ones like seen on a bally rectifier board or basically every connector in a WMS sys 6 game are .156.

THe smaller ones like on a bally MPU board or .100.

There is a lot of excellent information on Clay's site. Best tutorial on connectors that I have seen. Wally http://www.pinrepair.com/connect/
