I starter on a new project on a Bally can can and non og the fluorescent lights are working and I wonder what the problem can be since non of them are working at all?
Thanks for any help :thank_you:
-
Check the fluorescent fuses.
-
I have checked them, but since all three doesn’t work I m]was maybe thinking it must be a specific thing that are connected to all of them maybe?
-
don't have a schem for that game, but the configuration was the same on most games.
is the ballast shared by all of them? May be worth measuring the resistance of it.
getting 120V when measuring across a tube?
-
I need to learn this from the start I guess and I’m not good with the volt meter
There are three tubes and all of them have a separate ballast or what you call them, can it be the transformer (main power supply )
Where should I start checking since all of them not working?
Thanks again ;)

all of them not working could be a 120V issue on the coin door. The fuse suggestion was good, but afaik there aren't any fuses in the circuit besides the main power fuse.
the ballast looks like a box, the starter is a cylinder.
usually a white wire is on one end of the tubes. That's the voltage wire from the main power fuse. A black wire is on the ballast ... that's the 120V connection. You'd want to see if you have 120VAC when measuring with the meter on those two points.
you don't want to probe the wire between the ballast and the lamp socket. That wire may have much higher voltage on it.
you can swap around the starters / tubes and see if that helps.
starters are pretty cheap, but ballasts not so much. These days, people replace the tube with an LED tube since that can cost less than a ballast. You typically need to remove the ballast and starter and connect the black wire that was on the ballast directly to the tube socket. Easy way is cut out the ballast and connect the two wires together that was on it, then remove the starter.
pull a tube and get the part number off it, then google for an LED replacement.
you have other machines to borrow parts from?

Here’s some pictures of the machine and I try to find out where the power to the tubes come from so I can start to track it down, and I will also try to check the connection in the door, yes I also have several other machine so I can try other parts and I also have extra ballast starters and so on..
I also don’t understand what the loos end plug on the middle picture is, can that be something I need to connect maybe?
-
each flourescent tube has four wires going to it - two each end (call them A & B below)
a typical door fluorescent has:
A1] white (50) - 120V power
A2] orange/black (78) - starter
B1] red/yellow (13) - wire from ballast
B2] white/brown - starter
each fluorsecent has it's own ballast and starter.
I'd take a look at each fluorescent and see what wire colors are on the sockets, then trace the wires and see if the parts are missing.
your plugs with black/white wires are probably 120V ... stick meter probes on the two wires and see. The could be for optional parts not in the game.

Made any progress on the light situation yet?
Possibly the tubes are bad, previous owner might of not bother to
replace the lamps.
Check for discoloration near the ends of the tube. Dark grey is an indication the tube is old.
Possibly swap locations of the lamp.
Also the transformers will warm up if there’s power to them. Use EXTREME caution using the back of your fingers or hand to check temperature.
Check the plug in the door, particularly the colored wires Wolftalk mentioned. Also burn discoloration from internal heat.
