Reply to "Williams electronic eunit lockout switch modification"

Chuck and Stan - thanks for your replies. I wish I had seen the "Rev 4 only" note earlier. My board is R2, and although it is quite similar in appearance, there are some differences. It does not have the sockets (on the right end) as the one in your photo does. I also noticed that R1 is a different value, and the PWB foil patterns are different. So, thanks for the picture, that certainly helped to understand a very plausible reason why it's not working. I guess I'll just run it without a lockout for now.

I also noticed the relays are really wimpy! At 2a for AC and 1.25a for DC, I'm surprised the single MPC era Pullmor motor hasn't killed it yet! We'll see how long it lasts
