My Timex timer broke recently (plastic shaft inside snapped) and no longer will spin. I bought an Intermatic T101M as a replacement. Beside the fact that mechI got a super deal on it on eBay, but didn't realize that it was a SPST as opposed to the DPST that the Timex is. Which means that the terminal strip is different. On the DPST, there are 4 terminals, 1-4, with a black and white set coming from the breaker box and a black and white set going to the pool pump. The new timer only has 3 terminals, the A post and 1 and 2. How exactly should this be wired? Anybody else have this problem?
