Electrical gremlins (No headlights) V70-XC70 1998

posted by  someone claiming to be Boris on  Tue Jun 4 16:59 CST 2024 [RELATED]

I've been reading the wiring manual...it's only about 320 pages of technical lingo and no English description of part names. I like the challenge but this will be a PITA. I discovered something interesting. My headlight switch is removed, and on my work bench. I have no keys in the ignition. If I pinch the low beam contacts on the headlight relay I get the low beams.
Is it normal to have power on the headlight relay all the time?
That being said, which is the bigger culprit now, the headlight switch, the headlight relay, or perhaps something else? All the fuses are fine. The plot thickens...
