I have injectors out of a 2013 Pro RMK 600 after some testing and swapping around I determined the PTO side injector is not working or plugged. I'm assuming its plugged because the sled is a spare and sat for 2 years unused. Before I send them off to be cleaned I was wondering if there is a way to test them. I looked through my service manual and the diagram and the injector connection lacks any info on what wires do what. I can trace which two wires go to the injector itself but still would need to know what voltage it should be running at and polarity. One wire is Red with blue stripe and the other is blue with white stripe. If anyone has any info on this I would really appreciate it.
