Fuses are good.
Is low-beam ground separate from high-beam ground?

Looking at the plug on an H4 harness, which would be low-beam, high-beam and ground?


    (2) _
(1) [        ] (3)


1. Ground ,
2. Low-beam & 
3. High-beam?

I get ~2.4-volts between pins 1 & 2 on the harness.....hmmmmmmmm.............
>11-volts between 1 & 3, w/ high-beams switched on.
Sound at all familiar?

Thanks!
