Some interesting results from other owners here
Appears the majority have a low percentage of sustained magnet/ball hold success
So I’ve done some tests myself, I own a Munsters with the same magnet/ball hold function
This works 100% of the time, so I took the magnet core w/stainless protector (I checked the manuals of BM66 & Munsters, & both are identical “part number and description “) out of the Munsters and put in BM66
Also I took the magnet/connector assy, 22-650 out of the Munsters and put it in BM66
These parts are again identical and have the same sticker with matching numbers on each
So seeing that the magnet core assembly are interchangeable, I tried out BM66 with The Munsters magnet
No difference, BM66 only grabs the ball with a slow shot
So I’ve gone to absolute basics, checked my levels, magnet & turntable with the playfield
Also pitch (not too steep, just average)
Perhaps it needs to set up steeper?
Still performs the same, so it’s either code adjustment to strengthen magnet pull or it’s just the games design, for example:
The Munsters magnet is set back further up the playfield, perhaps this is the difference
as the ball loses some momentum once it reaches its destination
Those that say they get 100% ball hold onto the magnet on BM66, that’s awesome
I just don’t see how, if you strike the ball flush and hard off the right flipper
That shot is way too powerful for the magnets pull to stick
For the record, I’ve added some Mylar to the magnet, maybe improves the ball hold a little, still testing
