With 2900 plus posts hopefully someone can shed some light to a 80b newb.
Picked up my 1st 80b for my girlfriend. She is a gottlieb fan. But no 1812 or cactus Jack's floating around our area and budget. So we purchased a raven for fair price for shape. Perfect for her as she likes sniping targets over multiball. When I looked at pin it played with no sound and would shut down. To get into the car I had to pull back box.
Got home last night and immediately put it back together cleaning as I went. To my surprise game played fine full sound etc. The ramp coil was burnt up. Plunger could not slide through it. But we played like 6 games before it did a reset. Went to bed and dug into it today.
Lifted up playfield, removed ramp coil wires/taped them up until replacement coil comes and did the ground mod at transformer. The back side of the male bolt down part at the transformer did have some corrosion. Noticed a wire in middle bridge not hooked up with a non gottlieb wire that Is soldered in with the Gottlieb wire but I have no clue where it goes to. It is currently taped up.
Get done and go to play but no more power at the uncontrolled solenoids. Pop bumpers/flippers/kick rubbers. Controlled solenoids/lights all work. Can run through self test no issues
Have voltage at all my fuses found at transformer. I Checked ground circuit from playfield to transformer ground spot via voltage drop. Ground is good. Power supply in back box voltage checks out. Confirmed my 5v readings by testing chips on various boards to make certain they were reading same as voltage supply.
No power at fuse 12 through 15. No 5v at pop bumper boards. Can continuity test from respective fuse to solenoid and it checks out.
My eyes hurt from reading diagram on cell. But only thing that makes sense is tilt or game over relay is shutting coils down. Is my mysterious bridge wire tied into this?
As I type this the other thought popped up that me removing the coil for the ramp took away my voltage for other items? As ramp coil is fused on 16 on playfield. I unhooked coil and all 3 wires. I'm trying to find it on diagram but have not yet. I'll print it out at work to where I can read it easier.
So any input from the crowd?
Thanks in advance
