Quoted from stoli1:Well, to ensure you get the correct coil, you will first need to acquire a schematic. Another possibility is to email PBR and if you describe which coil you need and the name of the game you need it for, they might be able to help you out. As a last resort, if you can't find a schematic or get info from PBR or someone else, then you can measure the coil voltage at the transformer and if it is 26-30 VAC, then that coil from Marco that you linked to is probably a good bet.
I'd still try to figure out a way to test the 7 coil in place before you go through the trouble and expense of buying a new coil and pulling that bank apart to replace it. It would suck to go through all that only to find out the problem is with a switch or connector and not the coil itself.
1. Does one or two of the wires from each stack of switches go down to the coils below?
2. Can you access the solder tabs on the coils without removing the entire switch bank?
3. Have you tripped the metal plate on the 7 relay to make sure that the relay works physically, and thereby also checked the function of the switches associated with the 7 coil/relay?
Yeah, I really do need to get my hands on a schematic. Sucks there apparently isn't one available online to just go download. Hate to sound like a cheap ass but since I'm not keeping this after I get thing working, I'm trying to be cheap about it. Then again, since it's going to a friend, having a schematic for future use would probably be good. I highly doubt this is the last time I'll have to work on this.
I definitely need to test the coil and all that.. but it seems to me that I have to remove the entire bank in order to access the tabs on the coil itself. The board won't pull out far enough for me to access the back, unless it's just Jones plugs preventing this... I'll check that today.
Honestly I haven't had a lot of opportunity to debug much. I've been trying to get access to the back of the bank with little success.
Lemme see what I can figure out today and hopefully I can answer some questions. I might go ahead and just order that coil so I can place my marco order. I'm betting that, if that's not the right coil, marco probably doesn't sell it to begin with and in that case I'll be making a separate order with PBR, as you mentioned, anyway.
I really do appreciate all the help!
