I had a garage and was running a new power line since the old one got torn. The distance is about 120 feet and it supplies 3 light bulbs all (60 WATTS)The old wire was just a 12 guage no ground the new one is a 12-2. Inside where the wires connect is an old porcelin screw in fuse bus. I replaced the line and turn the lights on they were very dim. I checked all my connections, replaced the fuses and changed light bulbs still dim bulbs. The bulbs were bright before and i'm not for sure what may be going on any suggestions??
