    7.6 volts AC for FC with heater off. When I flip the breakers to off its 0.0 which is expected.

    I cleaned the ground wire connection. Still same problem. I just bought a true rms multimeter so I'll check the flame current soon. It's a cheap one though 20 bucks. And check gas pressure. Thank you for your guidance.
