Quoted from Mancave:
You might not need to replace it though. Unscrew the assembly that holds the the small coil from the bottom of the PF and have a look at the back of the bracket. It's like an L piece and there is another flat bit of metal on top that's sort of hinged (for want of a better term), this piece is what the coil pulls down to release the ramp and it has the little lock plate screwed to the end of it. My bracket was bent at the back part of the L (the upright part) and bent inwards which in turn altered the angle at where the lock plate engages with the slot in the crank arm. I straightened that part of the bracket up and had better results although as mentioned i had to stuff around with it a bit to get it sorted. I would also check that the front edge of the ramp isn't fouling on the side rail and that the large spring that adds the tension to the underneath of the ramp is clear as well. It's a tricky bloody mech and i must admit out of all the machines i've worked on that up and down ramp and also the cannon assembly is about my least favs when it comes to design.
I took the part holding the solenoid out, (like I had many times trying to fix it) and fiddled about and reattached it.
There were two sets of screw holes, one giving it more leverage.
I played it a lot yesterday and it didn't stay up once (that i could notice, still skeptical as I'm sure I tried moving it before).
Again, hard to explain mechanically and I don't really know what I did different that time.
I'll have to get pics next time I have the playfield up.
On another topic, the ball often falls off the whirlpool wireframe, I've tried bending the last side part up and away and still had it happen... Is that just part of Rosie?
Game is currently set on about 7 degrees incline, does steeper mean harder with Rosie?
And another subject, mine had been upgraded with LEDs, but the previous owner missed a few locations.
The GI is cool white in some places and warm in others (mainly where the old bulbs remain like flanking the left ramp under the plastics).
I'm feeling Rosie would look better with warm white GI, anyone have that opinion or thoughts?
