I am trying to trouble shoot a Square D 8 pole lighting contactor. Mechanically held, the part # on the face of it is 9998 LH44 0103. It is controlled by two 24 volt momentary contact SPDT (three way) switches, through two ice cube relays. The lights mysteriously stayed on recently, and won't turn off. I can make the contactor switch from on to off by jumping across the latch and 120v terminals on the base of the ice cube relays. I have replaced the relays, but can only get one to work. I am embarrassed to say, but I have very little to no experience in these, and how to trouble shoot them. This is for an important customer. Any suggestions, or ideas on where to go for instructions on trouble shooting would be GREATLY appreciated.
PS. I tried to attach pictures, but not sure if that worked.
