Output on Florescent Ballast?
I replaced the ballast and wired it blue-blue, red-red, blk-blk, wht-wht. I didn't realize that the new ballast wires in paralell, the old was in series. 2 blues on one end and red on the other with black and white as line. It did work for a while, but now nothing. Did I fry the ballast? Can I measure the output on the blue & red? Also, If I did fry the ballast, do I need to replace the lamp holder, since mine have a blk and white wire on each or can I just twist them together with the red wire? Thanks.
