Hi..brand new to pinball fixit hobby, I have acquired a 1986 Hollywood Heat, great game, $75 fairly good condition, wasn't working at all, replaced all fuses with new, and correct ones, new battery on MPU, cleaned it up, had a backglass backlit transparent film made, not like original...but I like it better... got most all lamps working, but still can't get right drop target bank to work, and if I manual reset they still don't register points, changed solenoid, jumped it and it fires, left upper bank works fine, it has an insync feature with left drop bank, but nothing works at all on right.....all lights work in test mode, but right bank reset doesn't fire, changed driver board, and now the fuse blows on startup, unless I unplug right drop target bank....Sorry, trying to give all the info I have, and I'm new at this hobby....any idea what to look at? My brain says voltage regulator, and I can see two of the old ones had burned the wood,....but.... I don't know, and bad idea to just keep replacing parts....fuses don't blow when I put old driver board back in, but right bank still doesn't work, test mode says Switch matrix 40 and 60 closed, solenoid test doesn't fire solenoid reset, I hear nothing when testing solenoid 3,6,8, and schematic shows that bank is solenoid 6, but left and right targets will drop in unison under test mode....Thank you for any help....
Jeff
