Near Intersection of I-35 & I-90 Southern Mn. | I'm not guaranteeing this but Raven was very consistent in their pin assignments. Generally the smallest pin - Pin 1 is ground IN while the largest pin number is 12V IN. So on a Raven 440/450, Pin 1 is ground IN and Pin 16 is 12V IN. I forget how many pins the 4600 uses but I'm quite certain Pin 1 would be ground IN and the largest pin number would be 12V IN.
The 12V Power IN will generally go to a fuse first before going anywhere else. If there is a fuse, you could remove it and check for continuity to the connector pins one by one. I'm betting it will be connected to the largest numbered pin. If so replace the pin and power it up.
