Intermatic Timers: Clocks not working

I know, you've seen it before, but I haven't found a solution. I have two timers, one for the filter and one for the sweep. The filter pump was replaced w a VFD a few years ago and I'm wondering if they wired the timers incorrectly. The clocks haven't functioned properly for quite a while, but I can't be sure when they stopped working.
Today I replaced both timers, assuming they were faulty, and rewired them exactly as before. In this photo, the filter is the left timer (which isn't used as the the drive is programmable) and the sweep is the right. The only change to the wiring I did later in the afternoon was to wire the sweep clock to the sweep timer, not as it was previously - to the filter timer. The sweep works when I use the Off/On switch, but the clock doesn't run. Could I have somehow fried both clocks?

Oh, I like that. Could I have fried the clocks? I guess I'll find out. Heading outside to do it now. Thanks!

So, add a wire like this, but to both timers?

OK. The two timers I bought at the Depot had 110V clocks, whereas the originals had 208V. I wired one clock correctly and it didn't run, so I guess I fried it. Oddly, I tested one of the 208 clocks and it seemed to run where it didn't before (which is why this all started). I'll replace clocks and report back. Thanks for the help.
