My bike has Oxford heated grips and a USB output / voltmeter from the PO, but that's all the electrical stuff.

**Item........................................... Load @ Idle ........... Load at 3000 rpm ...............Load at 5000 rpm**

Single headlight - Low Beam 3.6A 3.6A 3.6A

Fuel Pump (Continuous) 2.3A 2.3A 2.3A

Fuel Pump (Max) 3.8A 3.8A 3.8A

Oxford Heated Grips 1.8A Max 1.8A Max 1.8A Max

Regulator Current Output (Total) 24.7A 28.5A 31.2A

Battery charging Current 8.1 A 11.9A 13.1A

The heated grips seemed to have a square wave, so at 100% they would have 1.8A all the time, at lower %s they would be at 1.8A for a fraction of a second then drop down to 0A. The % of time they spent at 1.8A got higher with the higher % heating selected.

The voltage was displayed on the PO's little voltmeter display, which I think was the Regulator voltage:

Idle (1500 to 2000 rpm) 12.8V DC

3000 rpm 13.4 V DC

5000 rpm 13.5 V DC

I might try to check some of the above measurements, because there are a couple of things I don't understand

1. The lighting currents were the same at all throttle settings - I would have thought the current would drop as the voltage went up for higher throttle settings

2. I measured 31.2A total regulator output at 5000 rpm, where the output voltage is 13.5 VDC - that's 420 W. The regulator is only supposed to be a 380W device ...

It was good to see the battery charging even at Idle.

From all above, I reckon it is worthwhile replacing the stock headlamps and brake / tail light with LEDs, and that should give me enough spare capacity to run spot and flood auxilliary lights.

I'm still a bit suss about the ammeter I was using - I want to double check the above with another meter ...

Comments / corrections on all above welcome!
