Anyone familiar with the twilight sentinel set up...

[El Corvino]

Of all the components, which has the highest failure rate. I have 2 used switches and 2 brand new ones. Thinking that may be a bit overkill and I should be more worried about the photocel. Any input from experience?

Mine hasn't worked since the early 90's. Always thought it to be the photocell as they come on during the day if sentential is on. Some troubleshooting tips would be great.

Google usually works for me...
Looks to be some reading materials, as how to t/s the system.

I tried to google - wasn't sure if there were any major differences between this set up and the late 90's cadillac set up. That seems to be most prevalent in the searches online.
