Ballast change out

[trs4594]

There is an outdoor fluorescent sign that has 2 ballasts with 12 tubes. Each ballast supplies 6 tubes, each pin-set is fed by a color-coded pair of wires. Would a ballast changeout require the exact same wires from the new ballast to be connected to the exact same pin-sets or would simply supplying each pin-set with any set of color-coded wires meet the need? In otherwords regardless of color-coded wires (given the 120 volt input goes to the blk/wht), as long as each pin-set had a color-coded paired ckt would the overall need be satisfied?


Reason being the old ballast was cut out with intentions of splicing all the field tube wiring back together when the new one arrived. Pairs of orange-orange/white stripes, blue-blue/white stripes etc are simple enough. But there are about 3 sets of just yellow wires. Directions on the new ballast are easy enough but is there any chance of wiring these 3 tubes incorrectly? And if there is, it is as simply as switching a few wires around or doing a continuity check first?

Judgement check anyone?

The new ballast will have a wiring drawing on it. You must wire it according to the drawing. The colors may or may not match the old ones. You must be sure not to cross the wires so that the wires from a pair that go to one tube goes to 2 separate tubes.
