I have my Bally Playboy completely restored and need help with one issue. It has a new Alltek MPU board and new solenoid driver and led lamp driver board. Using diagnostic button everything checks out except a few bonus led lamps along with the left out lane lamp, the 20k, 8k and a couple more lamps do not cycle. Bulbs are good and when unpluged from the J3 connector and 6 volts is jumpered to the harness the bulbs all work. The 28 pin connectors were not replaced. Do I have a connector problem or some other problem. Thanks in advance. Bill

Those connectors are suspect. The ones that hang over the neck hole have a lot of weight pulling on them.
