Trying to resolve a problem for one of our neighborhood signs. Transformer is a Elegant Lighting Low Voltage Landscape Transformer, timer is a Intermatic DT620, hooked up to (2) 15w Mini Flood Lights. When I click ON, on the timer to manually turn on, there is a loud clicking sound, the display goes blank and the lights turn on, but pulsate. I've replaced the timer, starts to work fine, but eventually the same problem happens again. I'm probably on my 3rd or 4th timer. There is no way I've gotten that many consecutive bad timers! HAHA. Could this possibly be a transformer issue causing the timer to go bad? Anyone else ever have this problem? Thanks in advance.
