Title: Amount of Amps Put Out?
Post by SS65297 on 11/17/10 at 14:10:44

So I checked my service manual and all I see for the electrical system is the battery which is listed at 12V. I need to know how many amps the bike puts out altogether. I want to wire in my Chatterbox into the battery so it charges while the bike is running (The battery on it is terrible). Thanks.

Charge your what?   :-?
You did see the Mr and Mrs potato head commercial?
And you need to prolong that joy after you put your helmet on?
I wouldn't worry about the draw on that thing.

Search Chatterbox USA, its a communication system for riders so we can talk between us up to 5 miles apart. Would I be correct in assuming the bike puts out 8 amps?

battery is 1000ma and is good for 10 hours.
The draw is 100 ma not 8 amps.
Against the head light you won't notice it.

whats the load(draw) of your device..

my largest add on load is a amplifer rated at 3 amps..

only time i had trouble was with the oem 2 year old battery and i had the music goin for 1/2 hour with the bike off...had to buy a new battery that day...

P.S. have never seen a true (non guess) rating for the ls 650 charging system.

(2 ea 20 amp fuses on the bike)
my guess  20 amps  X 12 volts= less than 240 watts( ckts are fused at 125%  so 80% of 240w =192 watts)

to charge the battery the
charging ckt only needs to put out 13> 15 volts @ .75 amps
15 volts at 3/4 amp = 11.25 watts

there was a member here some time ago (savage greg?)was a sharp cookie bike mechanic had a meter where he tested the alt. output...
his test results may still be in the tech section somewhere...


its a shame the talent that has left this site B cause of a few A holes

I just need to know how many total amps the bike puts out. I am wondering how many accessories I can put on the bike. The draw is 10 amps from the device.

Don't quote me, but 17 amps rings a bell.

On edit, thats impossible.

10.27 Amps/210 watts at 5000 rpm w/14.75 volts
This is the calculation for a three phase alternator

Where did the 10.3 come from ?

210 watts divided by 12v = 17.5 amps,.....I was right the first time.
But then, it should really be divided by about 13.5 charging volts, which would bring it below 16 amps,.......and then lower the R's to a more average 3,000, and the amps will be less too.
