I picked up a Dirty Harry a few months ago and have been shopping it out but discovered a super weird issue. The left and right rollovers at the top seem to register each other. Hit the left one and the right one lights. Hit the right one and the left one lights. Using the flipper buttons to change lanes works as normal as does the middle rollover.

In switch test mode they register correctly (left rollover is left rollover and right rollover is right rollover). The wires are also wired correctly according to the schematic. I reversed the switch wires on the left and right rollovers, they register correctly but the flipper button lane changes works in reverse now (left flipper sends them right and vis versa). I've since re-wired the switches according to the schematic.

Has anyone had an issue like this or have any idea what could be causing it? Thanks in advanced fellow Dirty Harry colleagues.

Thanks a ton. Apparently the light board underneath had been switched around. The friend who helped me work on it just figured it out. Can't wait to get some more games on it now that it's up to snuff.
