Old Bally (1984) Flipper help

[pinnies4me]

Hey guys, got roped into helping a cousin of my wife with a flipper problem on a Black Pyramid. I've never touched a Bally of this vintage before. What I found was a broken EOS and resultant fried coil. I replaced the coil and EOS switch, but still not going. I've got volts at the coil, so must be a ground path issue. Cabinet switch is fine. As these go via a flipper enable relay, I am suspecting that - a few queries for Bally wizzes -

What's the chance the fried up coil could have damaged one side of the relay (the other flipper works fine)?
Is there a simple test method for the relay?
Are there replacements available if fried?

It is possible to have fried one side of the relay not sure how you would test this?    Maybe with a Multi meter check if your getting a signal out of the boards plug?

Could be the relay - Check for dry joints - Here's the path of the 43VDC for the flippers

J1 Pin 8 - To left flipper coil from Pin 4 of Relay
J1 Pin 9 - To right flipper coil from Pin 3 of Relay

J2 Pin 1 - To right flipper switch from Pin 5 of Relay
J2 Pin 2 - To left flipper switch from Pin 6 of Relay

It is a simple circuit, you may need to visually check the relay - It might be in a socket and if there is another Bally machine close by, you can swap them out. Check J1 and J2 on the solenoid driver board - refit just in case !

J2 Pin 1 - To right flipper switch from Pin 5 of Relay

We have a winner - track burnt and broken, I guess during the coil fry up!

Thanks guys!!

I was just about to say check for burnt tracks when you posted this.. i've seen that happen many times on these boards
