Thought I had it fixed but the problem came back. 73 fault car is level with the top floor landing. Ld info is high 125vac at cn1-8. Lu info low 0vac at cn1-7. Both LRD and LRU relays are picked. Seems like no matter what I do the car always has 125 volts on LDInfo even when LRD is high in the car. I’m leaner towards a bad HLsB board or a bad MRCB board but would like to prove it one way or the other?
