Hi everyone. I just recently replaced the lock relay coil on my Williams tropic fun and the game stopped working completely. The coil was broken and there was some serious hacking done to it so I tried to put it back to how it should be with a new coil. Now all I get is transformer buzz and nothing else. Any ideas on where I went wrong?

Lock coil isn't engaging at all? Not even when you hit the left flipper button? If you manually close the relay does the game turn on?

Ok so I’ve made some progress. Turns out the game is playing but it’s got no lights on again and the transformer is very loud.

No lights could just be one of the switches on the lock relay being mis-adjusted. Is it both playfield and backbox lights? Those are separate contacts on the relay.

Was the transformer this loud before? Are you sure it's the transformer and not the lock relay?

Ok so I’m thinking I did the coil wrong and that’s what’s buzzing. When I disconnect the coil and jump past it things work fine. I guess I need a schematic

Hard to hook up a coil wrong. Especially AC. Orange and black wire on one side, black wire on the other side? Unless maybe you physically mounted it wrong? Can you compare with other coils? Did you put the brass washer in? I assume it has one of those...

This is what I have

What color wire does that yellow one connect to? I see the orange and black down there but I can't see where it goes.

Can you get a picture from a different angle where you can see the screw holding the coil in?

It looks like there's less space between the top of the coil and the plate it pulls in than on the next relay over. Is there enough space for that plate to move in freely?

Did you clip that small green wire? Is there anything else going to the lug it's attached to on the right? Those two switches are for the backbox and playfield lamps.

The plate does appear to need more room so I’ll adjust that. The yellow wire is attached to a white wire that was too short to reach the new coil that connects to the same place as the orange and black wire. I did clip the green wire and I know that turns on he lights, I cut it because it was added by someone else and I wasn’t sure if it was shorting anything

It might be stock, if there's nothing else going to that lug on the right it's attached to. Sometimes williams just used odd rubber wires for short jumpers on the relays. If there's nothing attached to that lug then your playfield lights aren't going to work.

I hooked it back up and everything seems to be working fine after adjusting the plate next to the coil. That’s one problem solved now i need to fix the pop bumpers

The coil is also very loud but working

#13 2 years ago

If it's still loud it might still not be adjusted properly. It'll buzz if it's still struggling to pull the plate in, or fighting against the switches, etc

What's wrong with the pop bumpers

I notice the green wire has been cut? Never mind, already addressed.

One doesn’t work work and the others aren’t very responsive

Checked voltages at the coils? Should be at least 25VDC. Do the slingshots work fine? The circuit is really simple, just the coil and the one switch on each pop bumper, so there's not much else to do besides clean the switches and gap them nice and close. Can't hurt to rebuild the mech either but it should work pretty good without. If they're weak no matter what you do (including the slingshots), you might need to replace the rectifier
