I don't have access to my shop manual this week, and I'm eager to get some Gerbings heated clothing, but I can't seem to find the available wattage I could pull from the bike to power some new gear.

Does anyone know how much power is left from the electrical system to power things? Thanks.

Oh yeah, it's on '08 Fireblade, and I'm going to add a Zumo 550 next month.

These are just power consumption amount, i sure some one will be able to give the answer to the question using the above info

So exactly how many "gee-whiz" pieces of electronics will your bike power? Well that depends on a few variables. Basically, your bikes excess electrical capacity is the alternators charging output minus the common operating load. Usually these numbers are shown in "watts".
A "watt" is a unit of measure for electrical power (P). In this case, the charging power is the product of the bikes voltage (V) and peak current (I). So P = V * I. What this mean? Simple... if the bikes alternator has a peak rating of 20 amps @ 14 volts then the peak charging output is (20 * 14) or 280 watts.
A motorcycles electrical system consists of three major parts, the alternator, the regulator-rectifier and the battery. The alternator is responsible for producing the power to keep the battery charged and power all of the electrical loads. The regulator-rectifier converts the alternator output from un-useable AC power to useable 14.4 VDC. The battery is used to both start the bike and buffer the power from the alternator.

That's what I was asking. I know the bike puts out about 500 watts (courtesy of the Honda corporate site), but I don't know how much power the bike consumes on its own, and thus, what's left to power other things before it drains the battery. Was just asking if someone had the numbers from the manual handy, and I guess I'll just be patient and wait until I get home so I can just look it up.

I don't know whether to thank you or to curse you for typing all that out...

Copy and Paste mate

But that look like quite alot, 10Amps!
