Friend has an El Dorado pin, has an issue where the top bank of targets is not resetting after completion, and lighting special. Fuses are good. There is a switch operated by a bar on a piece if spring steel located in middle of bank which appears to be working.It opens the switch when all targets are down. I dont think targets are scoring either. Both sets reset on power on. I am told bottom targets do not reset during gameplay ,but this is normal. I see a relay for special, any ideas on where to look? New to the em game .... Thank you
