Hi everyone, my 400w m.h. capacitor start, just stopped..When I dissassembled the ballast..The only thing in there is a transformer, and a run capacitor..I am getting 120 vac as an input to the ballast, which is correct..but going to the bulb base, coming out of the transformer, I have 289 volts..does anyone know if this is correct? Is the bulb just bad, or is the problem in the ballast...? Thanks
