    Hi there,
    Im currently troubleshooting an early solid state and know that the out hole coil is bad ( probably the corresponding transistor too) but wondered if i could remove the coil and continue to troubleshoot the rest of the playfield? waiting for parts sucks lol.
    thanks

    If you know the coil is bad I would test the transistor, as it is likely bad as well.. when it is confirmed as bad just simply remove it. Start making your shopping list for the coul, a couple of those transistors (for spare parts in case you run into others) and continue troubleshooting.

    thanks. after looking at the schematics and identifying the transistor i was able to see the tell tale silver dot at the top where the black meets the silver tab.

    If any wires going to the coil are daisy chained make sure they're still connected to each other after you remove the coil

    does it happen to be the same coil as the knocker? good place to scavenge a coil while waiting for the replacement
