Turn the switch around.

If you want to wire ANY flipper coil so it isn't controlled by electronics then you will need a HIGH CURRENT EOS switch. The one installed on the flipper mechs you have (normally open) will have gold flashed contacts and IS NOT suitable for carrying the high currents required to act as an EOS in this fashion.

EOS switches for this purpose usually have tungsten points that can be filed to make good contact and will have much stronger leaves.

The EOS switch must also be N.C. (normally closed and opened when the flipper coil is activated).

You will need to buy some switches that are used in early solid state machines such as Bally Playboy etc. and fit these to your mechs.

Something like these:

"[...]the high-voltage always goes to side of the diode with the "bar". You'll also notice there are two coil "magnet" wires on the solder tab that is high-voltage. On the other two solder tabs, the bigger magnet wire is for flipper power, the smaller magnet wire for flipper hold."

So I supposed I need to find the big and the small wire....
