My son's 79' 280zx had HID headlights with projector lenses installed by the previous owner. In the past a headlight would go out and we'd replace the bulb or ballast and it would resolve the issue.
Recently however the driver's side headlight went out and I can't seem to figure out why. It's getting power to the ballast (a little over 12 volts) and we installed both a new bulb and ballast but no luck.
My question however is more in regards to the relay harness.
All over the internet I see where a relay harness is used but in the illustrations they contain only one relay and only one of the factory headlight plugs is connected to trigger the relay.
In my son's configuration, each headlight has it's own relay and both factory headlight plugs are connected.
Has anyone seen this type setup before?
I'm thinking I may have a bad ground somewhere, but I'm not sure where the second ground would be.
