Was trying to tower up and let Jib retaining rope out. Toggle on my remote was to the right on mast. Hydraulic motor would not come on and wasn’t able to let out the Jib retaining rope. Breaker Q940M was not tripped. Looked at my Erection aid and where S916S & S918S was just —- Which it should have been reading S916S. Switches were good, checked B911N (Inductive control detector of retaining winch) will also put —- if it’s not reading correctly. Had 48V at G27. K916A was not Acted on. Had 48V at K916A. Wiggled contactor and orange plunger on K916A was Acted on. Erection Aid was reading S916S. Hydraulic motor and Jib retaining rope started working. Need to probably replace K916A
