Howdy.

This is a Bally The Game Show built in 2003.

It's been blowing the fuse that has the lower kickers and the knocker.

My son noted that the kickers are more energetic than he's seen before. I pulled out the multi-meter and that circuit (along with the flippers) are showing 75v instead of 50v.

I've looked around but I can't figure out where to start testing. Would someone set me off on the right path?

Thanks,

Rob

How can this be built in 2003?
You can also look at the jumpers on the transformer, look at the white wire if its on pin 7 = 115 volts. Pin 4 is 103 volts setting and will give you about 12% more power when plugged into 115 volt.
I would take an ohm measurement of each coil on the affected fuse and compare them to the coil chart.

That's what the factory sticker says. "Bally Game Show 2003". A bunch of the internal parts have 2003 on their stickers. Am I misreading those? I guess that it could also be referencing something but not the year. Sorry, I'm new at this.

Thanks Grumpy. Will do. I'll report back.

Are you testing DC voltage, not AC?

75v is normal. 50v is the nominal (minimum) voltage. You have an issue somewhere else in the game.

By the way, Game Show was manufactured in 1990. You're probably seeing a serial number.

Let's see a picture of that sticker.

Thanks. You guys are right. That's the model number. D'Oh!

Thanks for telling me that 75v is normal. I didn't realize that it was 50v minimum.

The left kicker coil is the wrong one. It's a 23-800 when it's supposed to be a 26-1500. I don't know if that's important, but it is different than what the manual says. The 23-800 was a bit loose in the holder as well so I tightened it. Will order new correct coil.

The 26-1500 is at 15.2 Ohms and all of the 23-800s on the circuit are 5 Ohms which appear to be normal values.

Grumpy, the white wire is on pin 7 so 115v.

I'll replace the coil and ensure that all fuses are of correct type and amperage then see if it happens again.

Thanks for the info and sorry about the year confusion.
