I recently picked up one of these that keeps blowing the F7 fuse on power up. According to the manual it's the "50vDC Magnet(s) or special application. Any thoughts on what it might be driving ? I'll also note that I don't have working flashers on the top or the lower playfield sides but the flashers under homer and the dunk tank work in test mode.

Back to the drawing board a few fuses less. I disconnected all of the connectors at the flashers (figured it would be easier than pulling all bulbs). Both sides up front and the header. Still blew the f7. Disconnected the flasher harness at the board, still blew f7. In the flasher test the back flashers work (with F7 blown) but something in the circuit for the header and front flashers is bad. Something tells me this is going to be a challenge.

I'll also note that I unplugged all of the motors (both ramps, shaker motor and Bart) still blew f7. I think I need to order more f7 fuses.

In a classic case of "RTFM" I broke out a copy of the manual and looked at what ran from 50v. It's not the flashers (they are 20v) but it is the Dunk Tank (which in the manual is listed as "J10-P8 - This Game Only" hey go figure a special use. There is a non descript 2 wire connector that runs up through a hole at the back underside of the panel. I unplugged it and sure enough, no more blown f7's. No clue what it will take to get back to that coil.

Ok I'm starting to pull my hair out on these carnival lights. I swear that there is a relay or fuse or setting somewhere that is preventing them from working but damn if I can find it. I am more than open for suggestions. I have 20vdc at the bulbs (both header and up front) and in the flash test mode homers head works but the other 7 don't. I guess it's possible that all 7 transistors blew up but I find it unlikely. Past that I can't find a common link between all of the carnival lights.

I couldn't believe that EVERY bulb other than the ones in the back of the playfield were out so I took a known good one from the back of the playfield and started testing sockets......... are you freaking me........ EVERY single carnival bulb was out, like EVERY ONE, not even a single one worked on the entire game.

That did uncover that line 1 is hard on so I am guessing Q25 is bad and needs replaced but I can easier believe that one transistor needs replacing over 21 bulbs.......

I swear if I buy another "unique" machine from auction no matter how good a deal it is just shoot me. The used ramp motors I got both work (yay). The one (yes one) in the game does not. Bart motor tries to energize but just makes a humming noise so I'm hoping it is just jammed up somewhere. Replaced the blown shaker motor fuse and now it runs non-stop so adding a Q1 to the online order list.

I am either going to get this thing working, play it for a month and then part it back out or keep it forever at this point.

Does anybody have a leg leveler sitting around or know of another machine it was used on that I could swap because I'm not getting any results on the part number ?. I have one with a bent shaft. Thanks

The description is - Leg Leveler 1/2-13 3-3/4"L with nut CH-0066-003-00A. I'm guessing that these were used on any game that had casters and leg levelers (cranes etc). The part number isn't giving me any success however Amazon has a number of options based on the description.

I ordered some (non stern but close in size) from a seller on Amazon that should be here today and "should" work but I'll check and see.

If anybody is looking to replace their leg levelers I got this set of 4 from Amazon and they seem to work. Note that they do not come with the locking nut if you don't have any. I got the 1/2-13 5" long ones because the stock ones are 3 3/4" but there doesn't seem to be any issues with the extra length.

You can move it on it's side, the one pc of information I will give you is when you get it to your new location, before you touch that power plug open it up fully and look for every lost / misplaced / random token. I moved mine and didn't look everywhere (aka under the dunk tank, inside of things) and the tokens will short out all kinds of fun things on power up. If you need dimensions let me know and I will measure mine.
