Hi, Could someone please help me locate a problem? I purchased 3 of the above kits for outside ornamental lighthouse projects. 2 work fine, however the other has developed a fault. Initially everything was fine when turned on, then after about 5 cycles the on cycle became longer and longer until now the light is on continously on. Now when the unit is turned on the lamp illuminates all the time without any off periods at all.
Cheers,
Stu.
Check orientation of the electrolytic caps. As you have two working samples, it should be easy to compare voltages at different points…
