I purchased a used ultra 1200, at power levels -4, -5 the dump light always comes on eventually, either after firing for a photo or hitting the test button, it takes anywhere from 10 to 30 seconds, but always comes on resulting in over exposure of this light. any help would be appreciated before I return the light. thanks

It is hard to say what is wrong without inspecting it. However, it sound like something internal is faulty or out of spec. Due to the lack of availablity of the parts for these lights, we are no longer able to repair them.

You can try a few things like ensuring the power supply is properly grounded, remove any extension cords or power strips. Make sure there is nothing plugged into the RJ11 jack.
