Quoted from vindic8r:I'm getting 10 ohm across the 2nd (right) diode and 168 ohm across the 1st one. If I'm tracking on this properly, those readings are in line and the diodes should be good.
You tested the resistance of the two windings on the coil, not the diodes. As it says in the link, you must remove one end of each diode from the coil to properly test them. Diode mode on the meter.
Test the resistance across the EOS switch when closed. Should be less than 1 ohm. If more than 1 ohm, file contacts with something stronger than 400 grit sandpaper. Better yet, replace the EOS switch and the capacitor. The EOS switch has to perfect on system 11 games or you get symptoms like you're seeing. You did 75% of the rebuild, now complete it.
New EOS switches often need to be cleaned first due to oxidation. Test the new switch. If over 1 ohm, 400 grit sandpaper will work on a new switch.
