I bought a new J&J LED pool light this week and initiated the repair today. Had the same issue as many with the wire not wanting to pull through the conduit. I was contemplating pulling the ground wire out, but I read some online chats and I made sure the conduit was wet followed by about a cup of Dawn dishwashing soap. I sprayed more water into the conduit and then let the soap work for about 15 minutes. One tug and I almost fell down because it came out so easily. 15 minutes later the new line was pulled through. Great tip on the dishwashing soap.
