If the test harness is plugged in all the lights come on. Putting the test rom in I had some lights out, so I replaced the q-101 - q108 transistors. After doing that all work except for 2,6,A,E. I've checked the 7417 and 74175 and it appears to be working just like the other lights when an explosion is activated. I've checked all the edge connectors, and all have a good fit. iv pulled the explosion board and reflowed it and checked all the diodes on that board they are all fine. If anyone can point me in a direction to check id really appreciate it. All the periscope lights work and so do the sounds.
