Seeburg m100b selection problems

Sorry, no photo--best I can do is tell you it's "dead center" inside item 15, core stop bkt, assemb., in the CCU parts section of the service manual. Pull off your core stop bracket and examine it --- Ron Rich

Eureka !! See eBay Item: 302069120527 See the "hole" in the coil stop bracket--that's where the brass insert, MUST be--this one is missing also--probably why it was removed from the WSR ?? Ron Rich

Thank you ive had a look and yes mine has it. Im still no further on with finding the short circuit. Somethings obviously going to ground

Sorry--I have no other suggestions--really confusing that 2-WSR's are doing this--?? Do they both have their own CCU's installed, or are you using the same CCU for both ? Ron Rich
