I was upgrading the connectors on the driver board to trifucon and noticed on the J12 connector that the orange/violet wire was soldered into the orange/gray wire. The connection on the old connector looked bad. I went ahead and replaced into the correct location on new connector and.....
the flippers don't work and the lower kickers are very weak. I removed and resoldered to adjacent wire and now everything works as before.
So my questions are:
Why is wire soldered here?
Why did I get the results I got when wire put back in normal location?
Does this mean the other end of the wire is connected in a different location than it should be?
Looking at the schematic it looks like those two wires are essentially connected but if this is true then why did it act different when I wired it properly?
Thanks for any thoughts/help!
