ok i think im sort of understanding it now. the 2 ballasts were already wireed to gether and to a cap and wvwrything when i got them this is what it does.
there are 277v 244v 208v(all 3 capped) and a 120v.
the 2 120v are then put together with 2 black cords. one of the black cords runs to a switch and then from the swithc to the plug(hot) and the other runs up to the lights.
then there is a ground going from the socket, bolted to the ballast box and then up to the light fixture. i then screw this down to the fixture?
then the third wire going coming from the plug in is the common i believe. this wire is then connected to two other wires. they both say com then there is two wires that come out of the ballasts that say com and then go together and then run up to the lights.
so these are the wires i have running up to the light.
yellow--- from one cap
red--- from another cap
green--- ground
white---com
black---????????????
so i attach a yellow to one of the inputs and a the white to the other
then do i split the white send it to the other one with tthe red.
grounbd it by just screwing it to the cannopy reflector.
and the black???
