While resetting the Left Arm yesterday, we found the RQ2 MAGNET ON sign was not working. Jessie found a burnt relay in the circuit to control it. He replaced the relay and things seem to be working ok. He checked the rest of the signs and found both signs for the LQ1 and LD1 not working. We traced that down to more miss-wired 480VAC lines, going to the phase monitoring relay used to turn on the signs; leftovers from trying to correct the phase swapping done on the LHRS. We corrected the wiring and things seemed to be working ok. During this we found one of the new white phase monitoring relays gave an OK whether the phase was right or left handed, clearly not good.
