Same here. my D1 is my daily driver, and o I'm limited with time .. but I'm also working on a new (90mm)I/C & radiator frame to suit.
definitely needs looking into that light stalk!
Like someone posted earlier, you should try to test it out off car. try a new relay, hook up two main power wires to battery, connect all connectors in the loom, and then with a couple of short lengths of wire, apply power to the H4 plug end(of the loom, and NOT connected to car).
Easy done, unless you already have it all installed and routed through vehicle.
I tend to be suspicious of Chinese made products, and test them before I install(where possible).
Brother's light bar worked perfect. Brother in laws(as I mentioned earlier) had a clickety relay .. and mine worked perfect other than I cut the lengths of all the excess wires prior to installing and redid the plugs. But all tested prior to fitting.
With your light switch, when it's set to high beams and it turns off the lights, is this with the light bar still connected(at all)?
With the lights: if you use the high beam(stay on switch mode), it turns on the high beams, but turns off the low beams.
BUT!!
if you hold the high beam 'momentary' switch on manually, it turns on both high beam AND low beam.
So check to be sure that when you say you hold the high beam, it turns on both the high and low beams.
Basically, if the high beam fuse has blown(and I'd triple check it to be sure) what you describe is what should happen.
When you use the On(and stay on) part of the high beam switch, do the main headlights work properly, and then go out?
If so, probably nothing wrong with your car, and most likely nothing wrong with the light bar, or wiring or relay .. just a blown high beam fuse.
ie. it's always the simplest things that muck you about the most!
EDIT: also note and be mindful; if it's just the fuse, you need to ask why has it blown. ie. did it blow out with the lightbar install, or was it already blown?
So double and triple check all wiring in this loom, check headlights and high/low operation with lightbar loom disconnected, so make sure your cars headlight all work properly first .. then check the lightbar that it works before connecting to car's headlights wiring.
That is, if you have the light bar installed and it's loom routed through the car, you don't have to uninstall it. just use some lengths of wires as 'hookup wire' to hotwire the lightbar's loom
independent of the car's wiring.
