Electrical Q - How many amps can she supply?

Hi Guys. I can't seem to find technical info on safe max (current) output


QUESTIONS
How many amps can the SV650 (pointy 2003) supply approx.?

If the draw is very high for 1-2seconds (eg 22a) would the battery supply the difference or would it not and something (regulator/rectifier/etc) get v hot possibly with irreversible damage?



BACKGROUND
Im currently maintaining 3x sv650 pointys. 1 is mine, 2 are friends. On 2 pointys I have upgraded the horns to 2x fiamms (hi + low) run on a relay from Mr Suzuki's horn circuit both = 10a (5a+5a).

Friend no 2 wants an air horn. I have it + packaging sat infront of me. Its rated at 18a (12v) + worst case = 18a horn + heated grips running (3a ish) + charging nokia (0.5a ish). Whilst 22a will only be required for 1-3seconds breifly is this far beyond the safe capabilities of what she can provide?

Any feedback/experience welcome

No it's fine, connect it through a relay to a battery though.

Starter motor draws a hell of a lot more than a couple of horns.

I think you should be fine, but cant confirm for certain.

The more juice you use the less work the rectifier does, and so not get as hot. At least that my understanding of the way it works. It takes more work to pull down than allow through.
