Hello Ben,
Here's a site that may be able to source a schematic for your Daimler...its free upon request but not fast.
Free Wiring Diagrams
As the fault occurs when you are using the turn indicator I would start there. The dash light and cigarette lighter anomaly is quite strange indeed. I will search around for the diagrams this evening
and post again if I have any luck. I suspect you have a short (bare wires touching) in the wiring harness that is providing power to all the wrong places.
Hello Ben,
Well..I found several "for sale" (expensive) service manuals for your 1974 Series 2 Daimler but no on-line information... so I guess we will have to do this the hard way.
A wiring harness that chafes occurs when movement, long term vibration or mechanically actuated movement (Like a tilt steering column) allows the insulation on bundled wiring runs, to eventually wear into each other causing a short.
As you have described some very strange electrical anomalies, I suspect this has occurred, unless another culprit is to blame...like mice...they love chewing wiring.
So...what you will have to do is closely examine the steering column wiring runs working your way towards the fuse block(s)
The turn signal indicator is my main suspect for the power short as this is the how the fault is made evident...but where the power from the switch is bridged to the cigarette lighter and dash lights is the question.
As you do your visual inspection you may find insulating tape or plastic conduit that you will have to open up so you can separate and examine the wiring. As you free up the wiring (separate the individual wires from each other) periodically test for the fault by turning on the ignition (no need to start the engine) and try the turn signal switch. .
It you come to a place in the harness when the fault is no longer evident, you need go no further. Start back tracing carefully examining for the faulty wires.
Please post to let us know if my guess work...worked.
Regards and good luck.

That sounds like a earthing fault , it will need an auto electrician to trace as these type of issues are notoriously difficult for the home mechanic to find as the problem could lie anywhere in the particular wiring loom/system that feeds the dash controls etc , hope this is of help
SOURCE: Dash board green indicator light gone to yellow why
yes what does it mean mine is green is that good
SOURCE: Signal and brake lights
Igot the same problem on left side.The problem was the convertor for the trailler plug.
SOURCE: fuse/circuit breaker for cig.lighter/radio/dash lights
The heavy duty or 'circuit breakers' should be in the engine compartment, perhaps in front of the air breather.There are one or may be 2 inside behind the front side kick panels driver and passenger side, or under the steering wheel.

Hello. The symptoms you are describing are likely due to a poor ground. Temporarily install a new ground wire by securing a piece of copper wire to the frame with a self tapping screw. Use this ground wire along with the hot wire to see if each of these lights works. If it does, trace the ground wire back to the frame, unscrew it and clean up the metal with emery cloth so you reestablish a good ground.
