Ok I have a regular marquee light that won't work. I have replaced the bulb, starter, and ballast...still nothing. I measured 110v at marquee plug by the marquee up top(plug had speaker wires in connector also).
My questions are:
First, does it matter which black wire on the ballast goes to which end? I usually install exactly the same direction the wires come out to the same wires. This time one wire on ballast was too short so I swapped black wires to make if fit without splicing in longer wires. Could I have messed ballast up?
Next question, I measured straight from the bulb socket without the bulb installed and had 110v between a black on one side and white on other....nothing on the other two! How do you measure a 110v light from the bulb socket?
Thanks for you help
