Question 640 Adv stator capacity?

Cant find it in the manual(s).
Anyone know how many watts these babies put out?

I was wondering what I could power on my 05...GPS, iPod and perhaps a vest (35 watts)

Thanks

Thanks Chris!
Whats the normal draw?

If I am running down the hwy with my high beams on I expect there is some draw other than the lights....Perhaps enough left for my 35w vest?

Never had any issues running GPS, heated gloves, and a heated vest.

Do all LC4's use the same stator? I've always wondered what the diff might be between a non electric start like my '96 and a newer electric start model stator?

thanks again
The most I will be running is the vest and maybe charging the cell, or camera batteries. With the exception of the vest I dont think those other items draw too much

did you search for this stuff? flanny et al got the specs from the factory, Mack probably has this stuff around somewhere...

dig man dig!!!

btw, it aint much - not much free, especially around town.

and i hear there aint no room for a rewind in their neither..

I searched to avoid a scoldin and all i came up with was some jap-bike links aboot more windings

Don't feel too bad Surly, the search engine here basically blows....

try google and use the switch:

site:www.advrider.com

along with your search terms - it will only search advrider - works purdy good

Here ya go:

Basically 200W is MAXIMUM output. So you would get about 16amps at full RPM. At cruising speed (5500rpm), you are down to about 13.5 amps. The battery needs about 3amps to maintain good strong charge, so you want to keep your TOTAL amperage to less than 10 amps. Even then, at idle or cruising around town you are down to 11amps, and so if you had 10amps TOTAL, you would only have 1amp left for the battery.

So...bottom line. Add up all your loads, and keep it down to 10A total, and turn off the extras in town to manage load. (ie don't sit at a stop light iding with your heated grips on "give-it-to-me", and your 100W driving light balring)

Your headlamp alone is 55w = 4.6amp. Heated grips are another 3.5 amps, and roadbook/GPS/Accessory lighting=1 amps or so. So on my bike I basically have 9amps load, or 1 amp left for otther stuff. Also, in a subsequent e-mail, the engineer said that the accesory leads, and all lamps are on 1-10amp fuse, so you'd be running the risk of blowing fuses with too much more load.


Here is the engineers message.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~
Mr. Flannigan

I am responsible for the electric system of our bikes . I hope , I can
answer your questions .

To my information , the Adventures used on in the globerider story had stock
headlamps . For an other Adventure for an australien rider we made some
minor electrical modifications , like output for GPS and for charging
notebook battery .

Generator performance :
The generator / regulator output depends on engine rpm . Please see table
below
1500 rpm 9 A
2000 rpm 11 A
3000 rpm 13 A
6000 rpm 14 A
10000 rpm 15 A

Battery charge :
On a long trip your average rpm maybe around 4000 to 5000 rpm giving around
13 A generator output . Please make sure , that your power consumption is
less , around 10 A , to have some current for battery charging .

Wiring harness :
Our harness is made to minimum outside dimensions and we use small wire
sections .Other bike makers may consider KTM harness as too small .
With higher load , you may run into voltage drops problems . Voltage drop
can cause some problems :
* Bad light output , because lamp performance highly depends on
voltage
* Bad battery charge

I've found you need to run the load under 3/4 the rated output of the alternator to keep things working right. If you are talking about a stock Honda alternator, that figure is closer to 1/2 (they lie). Consider approximately 150 Watts available for your system. Most devices are rated at 12 Volts, but the system maintains 14 Volts to keep the battery charged. You may have to consider that when figuring load. For instance, headlamps are rated at 12 Volts so at 14 Volts, a 60 Watt bulb burns closer to 80 Watts. At 14 Volts, an 1157 tail light bulb burns about 10 Watts on the low filament (high filament is about 30 Watts). Since things like turn signals and brake lights are only on momentarily, they can be neglected. With the lights on (assuming you have a single 60 Watt headlight and a single 1157 tail light) you have about 60 Watts to play with or a little over 4 amps. Overloading the alternator within reason will not damage anything. It just requires higher engine rpm to obtain the regulated voltage of 14. At lower rpm's, system voltage drops below 14 and the battery discharges. If it discharges too often, it will go flat.

You can check the load with a Volt meter. With the lights off and the engine running, measure battery voltage with the engine spun up a little. That's the regulated voltage. It should be 13.5 to 14.5 Volts. Turn on the lights and observe how much engine rpm it takes to get to the regulated voltage. Add your additional load and see how much engine rpm it takes to get to the regulated voltage. If system voltage doesn't get up there or if it takes a lot of engine rpm, the system is overloaded.
