Had the playfield up today to check on some thing, closed it back up. Went to start a game, and now it has odd behavior. Upon game start, the score reels reset to zero, but the ball kick out to the shooter lane keeps firing, along with all four drop target resets. The 5000 bonus lite keeps alternating left to right, and the large red arrow stays solid on the left side, and blinks on the right every time the 5000 switches to that side. Any idea what to look at first?

Turns out it was two wires touching on the alternating relay unit
