Well the pool light went out a few nights ago and I troubleshoot it today. Seems the secondary on my Intermatic PX100 is open.

I've did a google search on this item and it appears to be about $70-90 US. Can I source a transformer somewhere to just replace it, instead of unbolting the box assembly?

Also, anyone have a wiring diagram...was wondering why the primary has three taps?...is that an unused center tap?

Thanks,
