I didn't want to hijack Shar's Comet post with the difficulties I'm having with my Comet so I'll start my own issue I'm having.
What it comes down to I have F2, solenoids, keeps blowing everytime I press the start button. I've checked every single coil in that game including the ones in the coin door. Checked all the transistors on the mpu board-found one bad tip 122. Unfortunately, it wasn't the issue. I had some problems with the "firework" flashers in the backbox. In particular, the flasher for player 1....There are 2 ceramic resistors under each flasher. One is a 5 ohm and the other is a 300 ohm. Well I metered them up; one checked 5 exactly and the other was 150. Huh, unsoldered it and then it checked out 300 again. Is there a problem with the socket? Could a shorted flasher socket which are solenoid controlled be blowing this fuse?
