Controller relay

I run into unforeseen problem with my salvage controller, the 2nd relay is not working like it should. The actual relay is in working order but the control circuit is not, how do i fix that any one knows? What happened is some how the common and N/O is not connect when the rule is on, but if i use my multimeter in continuity mode to test on common and N/O then the relay turn on. Like I manually connected common and N/O by my multimeter. Is there is microcontroller that over see the relay operation?
