Hello everyone ,
I went through the parts list of my Bally Mariner to check if the right coils were used (surprisingly at least 8 coils were swapped for the 'wrong' ones). What surprises me is that the list states 2 "Post" coils. One in the category "G" Relays (G-32-2500) and another under "Assembly Coils" (AP-31-3000). I did find the G-32-2500 below the playing area but couldn't spot the second one.

Does anyone have a hint? Or t least tell me what the 2 posts coils are used for - that would definitely make it easier to find them.

Many thanks ,
Constantin

Got it, thanks to a friend. So whoever else also has the same confusion: It's pretty straight Forward. The post (such as between the flipper Levers) has one coild and another coil to control it (mounted somewhere else, f.ex. on the "main board"). Can't be simplier .
