I lost my side marker and tail lights on the tractor. I've checked the f3 and f8 fuses and they're good. I have power at my light switch and constant power at the relay. The ground to the relay is good too. When I flip the switch I'm not getting power to the side and marker pins of the relay. Any suggestions? I've been messing around with it all day and getting frustrated.
