Hey guys I have a Williams Flash pinball machine that I have owned for about a month now. This is my first ever pinball so I am pretty much a noobie to pinball ownership. Here is my deal with this machine:

Was playing on it with a friend for a couple of hours when all of the solenoids in the game except for the flippers stopped working.

After consulting the game manual I did the diagnostics test for the solenoids just to be sure and they were indeed not working. I then checked the troubleshooting section in the manual which lead me to a fuse on the power supply board. The fuse for the ~40V supply to the solenoids of course tested open. I replaced this and everything has been fine with the machine so far….

What has been bugging me is this: Why did the fuse blow?

So I ask you pinsiders: Is this just something that happens sometimes with these older pinball machines? OR should I be looking for something that might cause more damage to my machine other than a blown fuse?

I did notice during that play session that one of my drop targets in the 3-bank was kind of sticking when hit with the ball but seemed to reset just fine. I think I will clean all of those plastic targets and the solenoid mechanism parts in both drop target banks (5-target & 3-target) just to be safe.

Thanks for any input

OK cool.. that is a bit of a relief Thank you Sir!

I tried checking in the manual for the fuse value but I couldnt seem to find it in there at the time so I just replaced it with same type fuse as I removed: 3 amp 250v sloblo

Glad you mentioned that because I need to look in the manual again to double check today.

I guess I skipped this page last night /shrug:

I have some of these 2.5a s.b's and will replace the 3a tonite Williams_1979_Flash_Manual.jpg

No sir I have not rebuilt any of the connectors nor have I inspected them super closely. I did disconnect/reconnect them all during transportation of the machine due to having to remove the head unit at that time. I will say they all looked good and everything was very clean...

Thanks for the tip I will definitely keep an eye out for this.

Cool! Maybe I will be as lucky as you were
