Glad to find this group and be apart of it! Now a proud owner of a Volcano! I've been researching, researching, researching, [enjoyed every moment of it how to care for it and be a good owner. Looking for answers to a couple questions.
*Please note: I'm pretty much a pinball noob. I did own a GamePlan old coney island at one point but it got damaged beyond belief in transport and I couldn't afford a full restore which it needed. Looking to try the hobby again with a system 80. I am new to being a Gottlieb owner and have almost no understanding of electrical tech and repair (other then how to remove parts, solder, righty tighty lefty loosy... Looking for instructional guidance, i.e. videos/posts/ or websites, on care like cleaning and waxing, repair and maintenance of system 80 Gottlieb machines. I do have tools to do repair work and looking to learn.)*
Q1[Non tech related]: The operator's manual included with the machine turns out to be photo copy of the original (probably from 90's considering the quality) and is missing many pages like the schematics. Where would I get a copy/original/reprint with all the pages? I checked Pinball database and they aren't allowing downloads and the Pinball Resource doesn't seem to have a copy (maybe I missed it).
Q2: When the game turns on, it loads a ball into lane where the ball is launched with the plunger. It will not accept credits or react to the freeplay button until that ball is launched and received down the drain. Afterwards it plays and functions as expected. Is that a normal system check action or is there something wrong?
Q3: The circuit boards don't appear to have acid damage, does have an external battery attachment, and seems to have the grounding mod talked about on Pin Wiki. The game turns on and accepts credits and allows play. The issue?
The credit/match led display and 3rd play display's green translucent covering on the backglass seems to be melting when turn on. What should be checked, investigated, or replaced?
Q4: I tried adjusting the pot/volume control knob and, along with the volume, the brightness of lamps and led displays in the backbox increased when volume was turned up, and decreased when volume was turned down. Is that typical? Ideas, thoughts concerns?
Q5: Am concerned that Questions 2-4 root cause may be related to power cable as it is the stereotypical cord that only has two prongs. Looking to replace it but unsure which is best suited or if changes are required based on that choice: 110v or 120v? Which kind should be bought? Also, if it is needed to be replaced, where should the grounding wire from the power chord be attached inside the machine?
Any recommendations greatly appreciated Have a great weekend!
