key west has a unique coil/magnet on the back door directly below the spotting disc. The coil is not in the manual. It's in the search relay #3 circuit and appears to be intended to help reduce arcing on the ABCD switch contacts.
there's a label to the left of it, but the picture I have (below) is not entirely readable. Says something like "this magnet … A-B-C-D button … clean by maintaining current at all times".
anyone have the game and either take a pic of the label or post what it says?
if the coil has a wrapper with a readable part number, that would be great also.
if you want to measure the coil resistance, need to do it with no balls in the holes and one of the ABCD buttons pressed...and spin the search wipers to make sure reading doesn't change.
the game also has a "red or yellow relay" to the right of the sounder coil that is not in the manual. Info in second pic below.
