Well, replaced all the bulbs in my spa light, but still no light...tomorrow I'll get my multimeter out to check the power situation...assuming its 120V to the light fixture, and the transformer inside the fixture converts it to 12V? Going to check at the GFCI box first just to see if power is making it that far... if it's getting there, will drain the spa, pull the fixture and see what's happening there... if there's power to the fixture, I would presume its a bad transformer which means light replacement, correct? any other thoughts/ideas anyone?
