ok, just replace the BR and see what happens
Hi @edsr - I think @pinballmania was suggesting that a weaker coil than the one used would rectify the issue as force of the kick being reduced, it wouldn't be able to travel back up the scoop as it is doing, this is what is causing missing balls as in most modes, it checks the opto for the ball being there and just re-fires the ball back into play, on the Sky Dive mode, however, it doesn't seem to check that opto and re-fire. I have taken the mechanism off to straighten recently and whilst it is slightly better (1 in 7 or so, compared to 1 in 3) it is still happening. In saying that though, not sure if I managed to get it 100% right, so may just require more "adapting". I have checked the plunger action, which is nice and smooth, as well as the plunger plastic on the end which seems to be in good condition, no mushrooming.
The locked on magnet is one of the accelerator magnets under the jump ramp. This is causing drains down that shot if not nailed as it comes back down for insta-drain. The opto's that I beleive control that magnet are not working either, haven't had the ramps off to check them yet, but I hear that it is a nightmare of a job. So was thinking of buying the magnet and the opto's just in case, but those magnets new are about £30!!!
