Charging & Volts

[Top Gear TVR]

At this time of year I am inclined to run with my lights on so I get seen and can see. At the same time I like the heater on and roof off.

How many volts do you have with the heater on 2 and lights on?

I get between 11 and 12 (indicated) when bowling along with lights on, heater going 10 to the dozen and stereo on. Worth noting I have a 200W powered subwoofer mounted in the boot between the rear speakers and an inline amp in the glove compartment and it hasn't dipped below 11 volts indicated (yet!!)
