Actually, it locks up when I put it into diagnostics, but I don't think there's a difference.

Read through every thread and pinwiki/clayguides, etc.. just looking for some guidance as to how to approach. Here's the situation.

All boards in this Taxi are brand new. Problem is the coil on the bottom right pop bumper was bad, so cooked the corresponding MOSFET on the new board. At that time, the coil would lock on as soon as I turned the game on.

Replaced coil and MOSFET, and now it does not lock on when the game is turned on, but does lock on when I put it into test.

Switch is gapped properly. Coil is brand new. Thanks in advance for any advice!
