After shooting a pump problem I found that the contacts on the timer were not working.
They work like a set of "points" it a "make/break" contact
Although they were making contact mechanically, the contacts for some reason were electrically insulated. I cleaned the contacts with sandpaper and they worked fine.
It worked fine for a week and now it's failing again.
I know I can replace the timer BUT what's causing this ???
My last pools timer is fine after 20 yrs and I never heard of an issue like this.
Is this more common than I think??
