I'm working on a Comet and am right now trying to decide how to deal with a decidedly funky power supply. Here's and overall picture of it:

I don't have any experience troubleshooting power boards (all of my games until this one have been kind to me in this regard) but have been able to identify some obvious issues.

1) Super hacked connections for GI power in wires.

2) Burnt connector for GI out

3) Extra jumper wire?

My current thinking is to just yank this thing out and buy a new one. Marco stocks this one: http://www.marcospecialties.com/pinball-parts/D-8345

I'm not sure if it comes with instructions or not. If not, do I need to install a jumper on the four-pin J9 and if so, from which pin to which pin?

Then there's the matter of my fried connector. I've never replaced one of these. What are they called? Is this a 9-pin IDC connector? Marco stocks these two connectors that look similar:

I can't tell if wither of these are the correct part or even if they are functionally different in some way.

What would you do in my position? Any help is appreciated.

You know what?...this is about every single System 9 pinball supply!

Any way you slice it, you're going to need to learn some repinning for the harness connectors.
If it were me, I would probably just repair the original, but my advice to you is to just go ahead with buying the new supply and fix the old one for a spare. A new supply will give you long term reliability and get you up and playing quickly. Then in your free time go back and fix the old one, which at least needs headers, 5V filter cap and fuse clips replaced. See the section on GI repair and connectors at this link:

I also would rebuild this power supply as these are all normal things I repair when rebuilding power supplies and you will end up with a better unit then aftermarket for half the cost.

That's what I suspected. I'm not in a big hurry and am not so into having more spare parts to store so I think I will go the rebuild route.

Okay, Gumpy. Got your PM as well. Someday I will learn how to do this, but now is not the time. I would love to take you up on your offer to do the rebuild. PM coming your way shortly.

You're making the right choice having Grumpy do the rebuild--he's a great tech!

Good luck with your Comet!

My friends Comet. He called me over to fix it when he bought it years ago. It had around 12 feet of brown lamp cord and wire nuts in the backbox. It took quite a while to unravel, one of the wires came back to where I started, totally bypassing the fuses.

I've seen gold plated switches used instead of tungsten high voltage end of stroke switches. WTF?

Yeah, there's a whole thread of crazy hacks below. I mentioned the lamp wire one because it was just a spaghetti mess all around the power supply.
