Correct wiring procedure
I agree that a new supply would be best.. I have bought a 1600 Nomad that the driving lights were already fitted... What I don’t get is that many driving light are wired to be on all the time through the supplied switch on the light bar (as was mine)
I found that to be a pain as you had to turn the lights off at night and remember to turn them on again at night.
Here's my fix... easy for me cause I have a volt meter and wiring knowledge... but it not rocked science either ..
I purchased a 12votl relay and an "In line fuse" from autozone ... I ran a positive and ground wire direct from the battery to the headlight bucket... (didn’t have to remove the tank)
Run the driving lights positive to the relay negative to the new ground wire take the relay coil negative to the ground also. Take a wire from the relay coil positive to wire feeding the high beam filament in the headlight bucket..
The relay draws miniscule current so there is no extra load on your exiting wiring, and the driving lights have a good power source.
Best part is now you run high beam all day with all lights shining. at night you drop to low beam the driving lights switch off also as they should. This is the right thing for considerate and courteous driving.
