The easy way to test it is to get out your voltmeter and follow the
wiring diagram around.  Seriously, guys, you're there on the ground
with the problem and we're not.

You need +12 on the 30 terminals of the relays.  That +12 has to get
from the relay 87 terminals to the headlights.   On the ground side
you have to *not* have +12.  The dimmer switch has to supply +12 to
the relay 86 terminals, and the 85 terminals have to be grounded (or
vise versa).

The connections have to be good.  The wires have to not be cut.  The
fuses have to be not fused.

The dimmer switch gets its power from an alternate (unswitched)
source when you pull the stalk to flash the high beams.

That's really all there is, and we can guess about it all night to no
profit.  Go thou outside and measure.

Yours,
David
