Dodgy Right Headlight, Indicator and Horn. What thoughts?
Evening all.

As per the subject, I’ve got some electrical gremlins I want to sort out.

My right headlight (LED with halo daytime running light that comes on when the side lights are switched on), is currently yellow rather than bright white on the halo setting, and then projecting at funny angles on the main (not full beam), almost as if the light isn’t fully working.

In addition, when I indicate right whilst on side lights, no problem. When I indicate right on main/full beam, doesn’t work at all. And when I first switch on side/full beam, there’s a flicker on the dash board on the turn signal indicator.

And finally, my horn seems very dull sounding. Not a clear toot. In fact dull enough that some people don’t hear it.

This all sounds like wiring/power problem to me. I am a complete dunce when it comes to electrical stuff. What should I be looking for? And where? Dodgy wiring? Crossed wiring? Frayed wiring? Some servo or fuse problem? Etc etc

Help, as always, appreciated Thumbs Up Monsieur Le Grenadier

Sounds like you have an earth fault.

I think Andy is right, as it’s a fault that appears to be with different common circuits.
So that’s likely to be a high impedance ground.

So perhaps a battery clamp is loose, or the main ground lead is a bit loose on the transmission.
There are the other smaller additional loom grounds on the trans too. $W33T $0U7H3RN $UG4R

Thank you all. Seemed to have occurred after the gearbox was removed, so could be the one. Monsieur Le Grenadier

That’s likely to be one of those two ground points then, by the time the trans goes back in fatigue sets in. And the grounds are often just nipped up or finger tight which causes issues.

Not guaranteed but you never know, it’s a common scenario.
