gallaxy digi ballast

does anyone have one?
do you know what type of fuse it takes?
i just found the little glass fuse in my ballast and noticed it was burned up. i got some fuses that go into the lumitek ballast(a250v 10amp is what i picked up i believe) and they poped instantly when i plugged in the light.
does a good electrical man know why it might pop instantly?


in the meanwhile i got a magnetic ballast for a backup and to get my flowering going again. it sucks not having my light hooked up. lol
