Helping Paul install his VHO lighting into a canopy. At first try, the lights came on for a second then turned off... would have to unplug then replug ballast and it would happen again. We were advised to turn bulbs a little then try to restart the ballast, but we blew the fuse after a couple times. Purchased new fuses at Home Depot and have now blown out 4 new fuses instantly. Anyone know what could be up with these?
