Headlights aren't right, (very dim Lows, and almost no Hi beam) and it doesn't seem to be the fault of the aftermarket headlights.
Tested hi and low on both sides, at the connectors, w/ headlights unplugged.

RH side;
with lights on low: low beam wire shows 12V; high beam shows 0.24.
Lights on high; low beam and high beam show about 12V.

LH side;
lights on low: low wire shows about 12V, high is about 0.24.
Lights on hi, low is 12V, high shows 0.12.

The wiring under the hood appears unmolested. I don't see any obvious damage / tampering under the dash, but can't see much. The headlight dust covers have holes hacked in the back which are taped up: don't know what used to be in there.

What to test next?
All suggestions welcome.
Many thanks;
Alan
