....But I'm thinking that measuring the voltage in state: ignition on-not running, will be more useful if the headlight is off. ... I'll simply move the blue/yellow wire (with accompanying piggyback connection for the voltmeter) to the new relay as per your instructions and I think my objectives are achieved - right?...



I too thought after-the-post that now gives you four different current load conditions to measure voltage under - added bonus I think.

Not absolutley sure where your voltage tap is right now - if on the Blue/Yellow wire, then voltmeter will read for both lights on & off when you move to the new relay. I guess I thought it was on the output side.
It will also indicate the voltage while cranking of course. So there's 5 load conditions!

So yeah, sounds like good plan.
