Headlight dimmer, not dashboard dimmer, right ?  Although anything is possible,
I think it's very unlikely.  I've never seen one do that.  More likely a short
in the wiring on the load side, IMO.

I assume by "regular lights", you mean the low beams ?  Are you sure you aren't
turning the high beams back on ?

That does seem odd ... did you follow Dan's schematic ?  If so, how do you know
it's discharging (his schematic has no ammeter since Dan, like TeriAnn, doesn't
believe in them) ?

For maximum voltage to the headlight bulbs, Dan's harness (like the factory
harness) does not use fuses in the headlight circuit.  So one possible
explanation is that you have a short on the load side of the low beam relay
(between the relay & the headlights).  But that wouldn't explain why they work
after fiddling with the dimmer switch ... unless it's the high beams you see
work.
