Hey Musky ...Doc or anybody

What is the output of electrical system on the 1700??

I know it is higher than the 1600...

Tryin to figure out what bulbs we can and cannot use/where and when

using the formula watts=amps xvolts<br><br>Post edited by: Pop Rivet, at: 2007/02/05 07:20

Hey PR

Prety sure the Stator is 29 amp and the rectifier is 35 amp. Is that what you were after?

Roadie Dan on the R* Riders Forum would know. He's done a lot of work in that area.

Doc

Looking at my manual:

the charging voltage is 14 volts, 21 amps @ 5000 rpm

Rectifier capacity 18 amps withstand voltage 200 volts

One thing I noticed is that the headlight fuse shows 15 amps in the manual but on my bike it was 20 amps from the dealer with the Silverado Passing Lights. The main fuse is 30 amps. According to the wiring diagram the main fuse is first in the positive lead wire from the battery and all of the other fuses are downstream from the main fuse.

P=IE P=power (watts) I=current (amps) E=electromotive force (voltage)

(12 volts) * (30 amps) = 360 watts at the beginning of ignition from the battery through the main fuse (no stator voltage initially).

The hot lead of the rectifier connects to the hot wire in the electrical system after the main fuse. This rectifier output value is 14 volts at 21 amps at 5000 rpm.

This charges the battery up towards the 14 volts if the battery output is lower than the rectifier output. There is a regulator in the rectifier assembly to maintain the charging voltage. Since rectifier output is higher than the battery the current in the electrical system after startup should be supplied by the rectifier...Yes? If that is correct and the rectifier puts out 14 volts at 21 amps (5000 rpm) max the power available is 294 watts. Of course our rev limiter is set aroound 4250 rpm? So we get something less.

Didn't find the specs for stator output but the amount of power supplied is also going to be a function of the rectifier/regulator so We could probably get more power by changing the rectifier to get a higher amperage rating assuming the capacity of the stator exceeds rectifier output.

After leaving this post I was looking around and found this in the Yamaha sales blurb about the 2007 Roadstar. Do we have this on the 2006?

&quot;Factory-installed passing lamp relay speeds the installation of the accessory passing lamp kit available through Yamaha Genuine Parts and Accessories.&quot;

That is why i asked what year your bike was cause there is passing lamp relay on my 2005 Silverado and should be on following years the connector is inside the headlamp and I have pictures of it on my website it is white and has a P marked on it the dealer left it dangling and hooked my lamps up to the blue running light wire

Hook your passing lamps to this connector

14000 volts @ 5000r/min... did I spell that right POP .....Coug

Enough for the Griswalds

Soooooooo if our Rev limiter is set at 4200 rpms how the hell do we know what the output is at 5000 rpms....dam yamis good ???????and while we are at it why is the sky blue????? .....Coug

Okay here is the formula......plug it if it blows you cant do it .....Coug ......dont pass that formula around its a secret .....

The magnets turn around the stator that produces the AC voltage at 5000 r/min.
