Neither the headlights nor turn signals on my G3038H are working. Fuse is good, and I can hear the flasher relay working when turning in either direction. The combo headlight/hazard/directional switch seems to be fine (at least it connects pairs of contacts depending on the position). I cannot hear the dual headlight relay, but have verified that 12v is getting to it. Any suggestions? I hate to start throwing parts at it. Thanks in advance
