I wired my grill lights according to the attached diagram but can't get the lights to come on. Is this diagram correct? I'm not using existing wiring. Everything is brand new. The switch wire runs from the accessory terminal on the fuse box through a 20 amp rated switch and then out to relay connector post 86 and have voltage there. There is also voltage from post 30 to the positive post on the battery. The lights will work if I bypass the relay and go straight to the battery. I have five new 14 volt 30/40A relays that all test good. Ideas?
