Fireball Pinball Question

[grimbal]

This past weekend I picked up a 1971 Bally Fireball pinball machine. It's in decent shape and from what I can tell everything mechanically works on the playfield.

However I do have 1 problem and 1 question.

Problem: Something is causing the metal housing the glasstop to become electried so that you get a good shock if you touch it. However the coin mech door, plunger and power switch do not have this problem. Also sometimes you can play up to 30 minutes and just happens, other times you can plug the power cord in and not even turn on the machine and still get shocked. Now I've tried looking for exposed wires but couldn't find any. Anybody have any other suggestions?

Question: Is there any store bought cleaners I can use on the outside cabinet and the playfield to help clean them?

I've found a few things online but was wondering if there was anything store bought I could use.


BTW: Here's a pic of the machine.

there are cleaners and waxes specifically made for pinball playfields.

i love that machine. there was one in the club where i first met my wife, 11 years ago. the club has been closed for years, wonder whatever happened to that pin.... and the neogeo machine they had as well. argh.

On shocks:

Is the power plug a two prong, or three prong with ground pin? If it is only a two prong, then you need to replace it with a three prong. Run the ground wire (usually green) to the base of the transformer.

If this is not the problem, then check for a short somewhere that is sending power into the rails. Good things to check are the flipper switches, coin door parts, slam switches, etc.

On playfield cleaning:

Do a quick wipe of the surface with a cloth to remove any loose dirt. Then, apply a coating of Novus 2 (google that one, it's readily available and cheap). Wipe that down and see the initial polished goodness. Follow that up with a few coats of carnuba wax, and you're good to go for a good while. Depending upon amount of play, you'll want to do this again in the near or distant future.

Scoots - if you're interested in a Neo Geo, I've got a great 2 Slot available for sale or trade. Nice monitor and new controls. PM me.

Thanks for the info guys. It is a two prong power cord and from closer inspection of the power plug it looks like an after market hack job.
