I have one MAC 550 Spot that keeps blowing a fuse. I have had the fixture serviced recently and it still is blowing a fuse. Does anybody have any idea what could be going on?
Is it on the same circuit as other mac 550's? Is it blowing fuses while you try to strike the lamp? Are you striking lamps while other lights are on? I had similar issues with 4 mac 2ks, and the solution (and problem) was to strike their lamps in a staggered macro while no other fixtures were on. Striking all 4 at the same time in the lamp warm up cue caused a voltage drop too large for the fuses to handle.
It's not blowing when the lamp strikes, just during operation. Which is bizarre. I am leaning more towards a power supply issue.. There is only one other MAC 550 on the circuit.
