Hey Everyone
So I'm new to this whole process, so please bear with me.
I recently acquired a Gottlieb Spiderman 80 pin. Overall works great. I went ahead and replace some burnt out lamps in the behind the back glass and installed some leds in the playfield. After I closed the playfield and reinstalled the glass i booted it up. Everything worked great, however, the sound started to have a muffled effect....for lack of better terms. After a few days it cut out, made a high pitched squeal randomly, went back to working normal, went out, on and on. I changed all the fuses behind the coin box to make sure nothing was old or blown. Same issue persisted. The sound would work, go off, work, go off, and then while it was just on with no one playing it... it started making a sound like a dial up modem.
I'm thinking, with my limited comprehension of these systems, it could be a grounding issue, blown fuse somewhere, blown speaker or bad sound board. I'm leaning towards grounding since it comes and goes but these systems are known for grounding issues to begin with. I watched Todd's Tips and saw how he did the ground behind the backglass for the Gottlieb 80 system. The ones i can find online are $200 so trying to save some cash. Seems pretty easy. However I don't have any extra harnesses or wires laying around. So that leads me to my questions
- Does this sound like a grounding issue?
- Is there a wire I can buy at Home Depot to use as a ground for the harness as he describes?
- If so what gauge?
I apologize for all the questions but I'm very new to the pinball systems. I'm familiar with other computer repairs, midlevel electronics, and coding... but I always seek advice to make sure I understand what exactly is going on.
Also, if anyone in the Orlando area is familiar with this stuff and is willing to teach me and give me a hand I would be glad to compensate you for your time.
Thank you
