Thanks, didn't want to burn them out, I don't know a source for replacements.  They are stamped may 1981, so I guess they are the original ones.

like i said, you can apply the 12vdc first to see and of course the next step up is 24vdc, then if still don't work next step is 48vdc and if still not working, then its BROKEN  ;)


If you do it the revese, apply 48vdc and its a 12vdc, then it will get broken. If you apply 24vdc and its a 12vdc, then it will get busted...see the picture.
This option will surely make it not to work  ;D

First option is better.

Well as I had posted above, 12volts won't trip them, but 18 and 15 both will, was trying to figure out if I running them on lower voltage than they were designed to run at would hurt them.

You won't hurt it if applying a lower voltage. If your applying a higher voltage, then you can cook it.
So if 15 or 18 works, then use those and most likely, your coil is 24vdc so you can use up to 24vdc for it but don't apply 30vdc or higher.

If you have the silver Williams pinball coin door (as used in the early production run of Defender) those use conventional Williams pinball lockout coil (notice it is singular). If you have the black video game coin door on your game then it's a Coinco brand door. Coinco has abandonded the amusement industry and now only makes bill acceptors, creit/debit card readers, and vending machine changers so parts for what they previously manufactured are No Longer Available! :(

It's the coinco door I'm pretty sure, that's why I didn't want to burn out the coils. ;-)
