OK I tried all the connectors no luck? New symptoms found one of the lights in the speaker back box was out, thought it was just a lamp replaced it, when it came on it went very bright then blew, tried this a couple if times with 44's and 1847 lamps. Strange while looking under play field noticed the one bulb under Barts head was very bright compared to the others a 555, tried replacing it now it just blows. All the other lamps in these sections are working correctly, as in the speaker box area. I tried to measure voltage but these lamps flicker like they should so the voltage goes up and down. I'm not an electrical guy! Help? Also as I said before the left sling shot lights are out, but the right one has one bulb that looks right the other is dim?? These look like they are all daisy chained together, why no voltage at the other lamps? Both the lamps on the right sling shot measure 5.5V I hate electrical problems.....
