I have had a working fireball ii pin for a few months now. I wanted to replace some lamps, so I replaced one on the top of the playfield (when it was off). Turned it back on, and the lamp worked. I then moved the playfield in the service position to replace more lamps, in that process, it slipped a bit, a little wood chipped. So I carefully put it back in place, and turned it on to make sure everything was ok. (note, the lamp on the top of the playfield was 555 but the one I took out was 444. I realized after the fact.)

When I turn it on, the MPU light turns on, the squawk and talk board makes a quick noise, the scoreboard lights light up, two playfield lights briefly light up and the squawk and talk board LED flashes green for a second. I then noticed a ground strap was not connected to the speaker (pic attached) so I screwed it on to the speaker and used a multimeter to make sure it was grounded. Powered it on, no difference. I checked the bottom of the playfield for damage, I did not see anything. I checked all of the molex connectors to see if anything came loose, no luck. I also re-seated some of them. Where should I go from this point?

Thanks in advance!

Good morning Guppy1977 its a Bally. I accidently set that as one of my pins, I changed it. Good catch. I did not replace any lamps under the playfield. I simply lifted it up. But, I did notice where a lamp missing. I did not see any lamps fall out. BigAl56 On the MPU self test I get one blink followed by 5 rapid blinks, so 6 in total. I will go ahead and make sure none of the fuses blew out.

I attached a photo of the ground strap. It is nice and snug. This is the ground strap, correct? It looks like it is just a braid screwed onto the ground. It is nice and snug. I gave it an inspection to see if it ripped as well.

Also, are the 555 lamps ok to use in place of the 444 lamps? They fit but I do not want to damage anything.

Thanks guys!

BigAl56 Would the fuse be on this board under the playfield? I looked at them, and none of them look blown (no black tinge and the coils inside appear to be intact.

Thanks

Thanks tomdrum if a fuse isn't blown, i'm thinking a pinched cable or a loose connection under the PF may be the case.

One mention though folks, when you lift up the playfield, there is a braided ground cable close to where it slides when you pull it up. that was damaged but not 100%. I saw other parts of the machine that had solder on some parts of the braided cable. Looks like that may have happened and it was repaired that way. I put some soldier on the damaged part of the cable. Its all held in place well, I gave it a gentle jiggle to make sure it was on there good. I tested it with a multimeter and it was ok. But I am not sure if that braided ground cable shorted something out. I circled where I put solder. As you can see, looks like someone else did the same thing. They used a pretty big glob of solder.

tomdrum The cables are a tight fit. Is the cable I circled the ones you were talking about? A multimeter tested the same as you would on a non damaged part so I think I should be good.

****update****

F4 fuse is blown. My eyes apparently are not as efficient as a multimeter when it comes to checking fuses. Lesson learned. I'm hoping I can snag one from home depot instead of having to order one. I miss Radio Shack

Guppy1977 you nailed it.

You guys are both gentleman and scholars. I appreciate the help! ***FIREBALL AWAITS YOU.......*** lol

Does anyone know if this will work?

Thanks

When I lookup AG fuses, they are fast blow. But this fuse looks like a slow blow. Maybe someone accidently put it in?

E-00133-0005 is the bally part number for the F4 fuse.

http://www.actionpinball.com/parts.php?item=FUSE5A I looked up the bally part number and saw this. Which is a fast blow. The manual for FBii describes the them as AG, which I believe is quick blow. Super confused at this point.

I put a low blow fuse in there and it fired right up. I just went off of exactly what the documentation asked. Which is 5amp 32 volts. Case closed.

Thanks BigAl56 Guppy1977 tomdrum frenchmarky for your help!

Guppy1977 I was pretty tired when I posted. Correction, I put in a 5 Amp 32v fast blow per the fireball ii manual. I have the original documentation. So I went with that. I did see that the whitepaper you sent said 6 Amp fast blow.

Someone had put in a 5 Amp 240v slow blow (the one that I posted). So I was like, whatever, won't hurt to put a fast blow in place, and the documentation says that's what it wants.

I've had it for about 3 months now. Finally serviced it. Sqaulk and talk is recapped and working now, replaced about 20 lamps, all new rubber rings, cleaned the playfield and glass. I play this thing more than my new Stern that is worth 3x more. By far my favorite pin. Last thing I need to do is fix the fireball bonus. That's another rabbit hole I'll be diving into.
