Don't alternators used in 12V systems really put out closer to 14V ?
And with voltage drops, isn't the charging circuit closer to 13V ?
And I thought a fully charged battery is supposed to be around 12.8V ?
Here again, oh to have that tachometer on the Touring.
Let's see:
1) headlight (single) on low: 90W
2) driving lights: off
3) heated vest & gloves (@100W) x 2 x 50%: 100W [note this is variable -- rarely, even in the coldest weather can I stand to turn this up past 50%]
4) engine coils: ???
5) cooling fan: I discount this, placing it in the same category as starting -- it'll come on when stopped, and the alternator is at lowest output, then when moving, airflow takes over, and battery is topped off
6) navigator: 1W
7) heated grips: ???
8) McCruise control: 5W
9) fuel pump: ???

At night, add in driving lights - 40W x 2: 80W
Some high beam: +40W
