I have built a small rock water feature using a 12V bilge pump as the circulator. I purchased an Intermatic 12V light timer/transformer to power the pump.
There are two connection terminals on the timer which I assumed connected to the two wires on the pump.
When I connected the pump to the timer the pump ran rough and would not pump.
I checked the pump on my car battery and it ran great, fast and smoothly. I connected one wire to the + terminal, and the other to - terminal.
So my question is how should I correctly connect to the timer terminals?
