Quoted from mwelliott99:Does this wiring go through the ‘U’ relay? Anything else obvious to check?
Hi, yes it does.
Both left and right flippers goes through the 'U' relay, but of course using two different circuits.
Poor contact at this level can froze the flippers.
For the left group : the wire (088 - black slate slate) comes from the left flipper button, then pass through the connector A12P7/A12J7, and then through another connector A12J8/A12P8 and finally arrive at the 'U' relay.
On the other side of the relay, the wire (233 - red orange orange) goes to the coils.
Either a problem at the 'U' relay level, but may be also, check the A12P7/A12J7 connector (used only by left buttons/flippers).
