I'm working on an Elvis with a bit of an odd set of issues.
The Right flipper keeps going out. It has blown the trace clean off two SDBs! The coil has been replaced, tested, replaced again for good measure, but every time the same results. The hold isn't working and the coil machine guns, then in a few moments it will pop the q16 transistor and lock on.
For the life of me, I can't seem to figure out why it is doing this. It has done this one two separate SDBs and three coils. The EOS switch seems to make no difference either. Is there something to the circuit that I am missing?
