Thanks Tim. Can you please expand on your second point? I'm no auto electrics expert, but looking at the GT wiring diagram it seems to me that the voltmeter is still wired in parallel with the headlight circuit, even with the relays added, so why wouldn't it still accurately measure the potential difference between the +ve post terminal on the starter solenoid and earth?
