I just finished installing a new ballast in my in-laws 2 blub florescent fixture. When i turned the light on only 1 of the 2 new bulbs lit up. I thought maybe i wired something wrong so i looked again and it looked good. I took the blubs out and switched there locations and only 1 bulb lit up again. The same bulb lit both times regardless of its left or right location.
Should i assume that the 1 bulb that didnt turn on in both the left and right side of the light is bad? Thats my only guess but since its brand new i am second guessing myself.
Any other ideas?
