Troubleshooting light fixture and replacing. If there is bad wire the price will change. If there is a problem located in another area we will have to move up to a standard troubleshoot. Found that the fixture in the closet had a broken pool chain so went and supplied fixture and installed a new one with a pool chain and globe and everything worked with no issues and customer is happy about light. Five year warranty on the installation. Explain the problem with having a two wire system and why it is so important to have corrected and protected by a GFCI breaker and also explained aluminum wiring. Everything is working at this time. Micah is calling me tomorrow after talking with husband on which direction to go with solutions.
