I've got the above woodrail machine with missing flipper coils, switches and bats. I can sort the latter parts out but, there is no schematic for the machine so I don't know what flipper coils should be used. I found a bag of junk inside the machine, including 2 burnt out FL21 .....missing text..400 coils. I'm sure these are used in later Williams machines but not these? Have these burnt out due to incompatable voltages?

All the connecting cables that fed the coils and eos switches have been cut off too so if you could perhaps post a picture or two of how they should be connected up, that would really help. Maybe the FL21s were fitted and would have been ok but incorrectly wired so cause them to burn up?

All the pop bumpers suffered a similar fate but I can see how they need to go back,etc so it's the flippers that are the main problem.

If anyone can shed some light on this, I'd appreciate it or better still if you have a schematic with a coil list to see what flipper coils this one uses?

Thank you

Thanks Rolf.

The Shangri la schematic shows it as using the FL21 coil, but my machine is some 10 years earlier and finding information on it isn't proving easy. Kick off is the standard machine for the US market and mine has the European version with the word 'Soccer on the backglass, placed where the original Williams name was. The playfields however are identical so would use the same flipper coils.

I took a brief look on the various part supplier websites and Marco show the Fl21 coil as an em Williams flipper coil but I'm reluctant to fit these in case they are wrong. I'm sure I read somewhere that early Williams machines used a 50v supply to some coils which might well explain why those two burnt ones were laying in the cabinet, presumably overloaded?

Thanks, Rolf. That's interesting, thank you. I will dig a bit more to see if there are schematics that list the correct coils.

Here's a link to the machine in question: http://www.ipdb.org/machine.cgi?id=5188

I'll report back with how I got on...

I looked through Clay's list of Williams machines and found, via IPDB, a coil chart for a machine of a similar vintage and that shows the coils as being FL25-930/31-600 so the ones that were inside the machine are obviously wrong. I think these later ones have the winding at 400 as against 600 so the resistance is quite different and could explain why they were burnt out

I have another Williams of a similar age in store so I'll rob the coils from that one for now so I can get this one done, and order some new ones from PBR.

Thanks again for your help.
