Hello JohnB....I was wondering about the same thing awhile back. Here's the link to my original question and the answers I received....

Hello John....my supplier still shows the boards as being available and I have some listed on eBay. Here's the link...

Hello Lee and thanks for your reply. The board is for a mail order customer of mine and I'm not certain of his intended use...he likes to tinker. He may have only needed to know the the boards electrical limits. I'll pass along the information....Tom

I have a customer that would like to know the electrical ratings for the Williams by Bachman #00249, Reverse Board with Lockout.....amps etc....Tom

Joe, Len and Lee....sincerest thanks for the thoughts and suggestions. I just got back from Radio Shack and will experiment with the board. I'll post the results here....Tom

Hello Joe....I set the multi-meter to 20 ohms and got results for connected pins as marked with the color coded Xs in the photo....Tom

Hello Joe....thanks...those are easy alternatives that avoid the board entirely. I'm still curious about those sockets though. Bachman must be planning something or they wouldn't be there....but then again who knows. I'm surprised the service rep didn't have a clue......Tom

Hello Joe....Laura Harris at Bachman's Customer Service indicated that the sockets in question "are not for any use at this time". I have the board and a multi-meter which I've used in the past to check for open circuits. The reason for my question was to help one of my customers who wondered if the new board could support a back up light. That 2 pin socket at "A" looked like a possibility. But if they're not being used, the other 2 pin sockets may be options as well. Perhaps I'll wire up the board to a couple of motors and check the output of the sockets with a bulb....Tom

Hello Group....I'd be grateful if someone could ell me the functions of the sockets labeled A, B and C on the attached photo. I looked through the related information in other posts but didn't see an answer...Thanks....Tom
