[urq] High beam indicator stuck on, high beam stalk has no effect- what did I break?

[Keith Lloyd]

Hi Steve
I don't think I can help re the main bean light staying on with returned to 
stock wiring but I can tell you that I made myself a headlight wiring loom 
from a coupe  quattro donor car loom and relayed the lights taking power 
direct from the alternator and taking the main/dip feed to trigger the 
relays from the now redundant original main beam plug. And I had the same 
issue i.e. having switch the main beam on, it would not them go off unless I 
turned the lights off all together (although the dash main beam indicator 
would go off) . Also dip beam would be on on all the time even on side light 
setting.
I still have the issue but rarely use the car at night so it's not a 
problem - but it is on my list to fix! I guess it is something to do with 
the live feed triggering the relays.....??????
So what I am saying is that whatever your loom suppliers provided you with - 
it's probably been done properly in terms normal wiring on normal cars.... 
but there is something odd about urq wiring they and I have not yet 
fathomed. Perhaps a shared feed with dip beam or something odd done with 
earthing to switch main beam on and off???? I hope someone on the list comes 
up with the answer because relaying is the way to go...makes it like 
daylight. Unfortunately oncoming motorists don't share my enthusiasm.
All the best

I had Susquehanna Motorsports build a relayed harness to properly power the
euro H1/H4 headlights on my 85 UrQ. Unfortunately the harness had some
wiring issues- the high beams would latch on and not shut off unless I
turned the headlights off completely.

I wasn't happy with how I had the harness powered and routed, so after
using it on the drive up and back from Winter Driving school I've pulled
the harness out of the car and only have the low beams connected. Despite
putting the wiring back to stock, the high beam indicator is on all the
time and pulling on the high/low beam stalk has no effect. I can't really
tell whether the highs are really on or not because they're not connected,
but the high beam indicator certainly thinks they are.

Did I fry the stalk, or is the problem potentially somewhere else? I
checked the wiring diagram in the Bentley and there doesn't appear to be a
relay or anything else involved in switching between high and low. All I
see is power from the switch to the stalk, and then from the stalk to the
headlights- I was expecting the stalk to trigger a relay somewhere, but
there's no evidence of it I can see in the wiring diagram. Am I missing
something? Any hints would be useful- I've created some adapter harnesses
so I can wire in the high beams, but I don't want to wire in the highs if
I'm just going to blind oncoming traffic.
