Quoted from Mudflaps:

I learned that I suck at soldering. I also learned (again) that pinball machines don't like to be moved.

So true.
We just moved a Xenon we are working on. It was booting perfectly.
We moved the machine from one side of the room to another on pinball skates, so it was smooth ride.
Now all I get is a loud hum from the speaker and the main board no longer boots up. Arrrrrrgh.

Quoted from ForceFlow:

Are you sure that the outlet is grounded?

Funny you should mention that.
The section of the room that we moved it to still has wall outlets with no ground. So I had to use one of those little adapters to plug it in.
Did not realize that it would effect a 80's Bally that way so maybe that is it.
I have had other games plugged into that outlet with no issues in the past.
But I will run a cord to a properly grounded outlet tomorrow and see what happens before I start messing with the boards.

Quoted from swampfire:

I learned that early Bally/Stern power supplies are much easier to work on if you remove them from the backbox, transformer and all. It's only 5-6 screws. And, you can connect it to 120/240VAC right there on your bench (but be careful, of course).

So Glad I read this.
I was wondering how hard the power supply was to move.
I am working on a Bally KISS that needs a new power distribution board located right over the power supply.
And to make it worse all the wires on the backside of the board must be soldered in place. Arrrrrrgh.
Nice knowing I can easily remove the whole thing for bench work. I was not looking forward to soldering in the tight little space in the head.

Quoted from swampfire:

I actually did do that with Skateball, and I feel dumb now. I replaced the entire GI header while standing painfully to the right side of the game, ugh.

Yea.
I put all the new molex plugs on while standing off the the right side and my back was killing me.
But at least I can now do the backside of the board in comfort.
Any tips on putting and soldering the wires in the through holes is appreciated.

Thanks to this thread I got my Bally KISS power supply out of the head with ease and soldered on a brand new power distribution board.
Here are some photos just in case anyone else is thinking of attempting this sometime.
If I can do it, anyone can.

Learned this today.
Had a small screwdriver in my hand while testing the continuity of a fuse I had removed.
If you put one lead of the meter on one end of the fuse, and the screwdriver on the other end of the fuse, it will test bad every time.
When I finally realized what I was doing it took about 5 min. Just to stop laughing at myself.

Quoted from markp99:

I have a gremlin in my workshop that keeps hiding my tools each and every time I put them down.
Damn, I just had that hex driver; where'd it go this time?!

Just cursing that gremlin yesterday.
