Hello everyone, I am new to this forum and also new to repairing and modifying pins so please take it easy on my rookie ways. I am currently working on a Gottlieb Volcano (series 80), during the process of a full LED swap I ran into an issue. Starting at the beginning i swapped all the backbox lights with no issue. Next i went after the playfield GI swapping all the bulbs from the top of the playfield with the unit plugged in but powered off (based on the note in the backbox stating to do any repairs or swaps with the unit plugged in ). After swapping all the playfield GI i powered on to check my progress and all play GI was out, all the other lights in playfield as well as backbox are all still working. Checked fuse, sure enough it was popped. removed all bulbs from GI and replaced fuse.... popped. so bad bulb is eliminated, suspect bad socket. checked continuity on empty sockets and there is a complete circuit on the empty sockets (this would mean a short somewhere correct??) next I removed the end wires from each group of GI sockets (the ones that connect to the tip of the bayonet bulbs, not the bare wire stapled onto the playfield and connected to the chassis of each socket). I believe i have every connection separated from the sockets. Now checking continuity on each individual socket reveals no connection, so no shorted sockets. But if i connect to the loose wires and any socket chassis i get a circuit. I did notice one more connection using the same wires i disconnected from the sockets which is on the leaf switch operating the ball save gate next to the ball shooter but that appears to have no bearing on the current issue. So this leaves me at the current completely lost position, I am under the assumption that the playfield GI is not connected at all to the Circuit boards in the backbox so i have mostly ignored that area. Attempting to trace the wiring (i dont have a manual) it appears the fuse runs up to a series of solenoids with leafs on top of them under the playfield (blue black black wire from fuse leaf switches to purple slate slate which is the wires i disconnected from each GI socket and continuity agrees), now the purple slate slate wires do jump from one solenoid/leaf to the next until they join the main wire harness running into the playfield and on to the sockets. Is there a section of this circuit i am overlooking or a component that i should check for a fault?? I am completely baffled since nothing was moved, i didnt even lift the playfield till after the issue showed up, only swapped working incandescent bulbs for LED bulbs and now i have no lights and endless fuse pops. Please help with any info or places to look, i understand there is a trick with soldering a bulb to a blown fuse but if i am understanding correctly that wouldnt do anything in this scenario since i have already isolated all of the sockets from one end of the circuit. I can provide pictures of the solenoid/leafs or any other component or area if that would be helpful. Thank you all in advance!!!
