Under the Troubleshooting Tip for a (Williams) SFL-19-400 coil within the Marco website appears the following statement:
"If your flippers are weak, ensure that your end-of-stroke switches are...set so that they are normally open when the coil is at rest."
I own a Black Knight (1980) with four flippers. On my machine each EOS is normally closed when the coil is at rest; the switch opens when the coil pulls in. However, I interpret the flipper schematic to show the EOS as normally open (image below).
So what gives? Is the Marco tip incorrect? Is the schematic? Is this game..?
