Ok I'm baffled.
I had previously replaced the scorched fliptronics board and a suspect coil with a new rottendog and a new coil. When that didn't work, I put a /second/ new rottendog in.
Then I put in a second brand new coil and then a brand new rottendog power driver board in. I double checked the wiring at the coil. Fuses are good.
When I turn on the game the flipper did /not/ lock on. But I started a game and got no power on the flippers. All other solenoids tested.
While the power was on (but a game wasn't started), I tried to move the right flipper with my fingers and /then/ the flipper locked on. Powered it off, then it went down.
What the heck is going on???
