Looking at a enlighten empower sauna that has me scratching my head. Sauna is 240v with a android touch panel, stereo, led tape light, and 12 volt interior lights. The lights are mr 16 style that can be replaced with a chromatic style lamp ( something to do with therapy) in the process of changing lamps a shock was received, duct work was touched at the same time as metal ring of lamp was touched. I attached a wire from the neutral ground bar in the main breaker panel and with my meter set on ac volts I get a reading of 38 volts, if I set my meter to dc I get a reading of 140 volts. I also drove a ground rod 15 feet from the panel and took a reading from jumper wire to ground rod and have zero voltage. I also produce the same reading to the metal case around the radio. The mr 16 lamp holders are bi pin with the leads going to the floor where the power supply is located. The therapy lamps in question have a led circuit board/disk integral to the lamp that allows them to color change. All breakers have been shut off except for sauna breaker, voltage remains, shut off sauna breaker voltage disappears. Any suggestions? Supplier will be contacted in the a.m.
