The Alt is spec'ed at 280 watts @5,000RPM

Head light is 55 watts
brake Light is 42 watts (when on)
Tail light is 10 watts
Position light is 5 watts
Instrument lights are Approx 6 watts


Unknowns are the fan motor and the Ignition.

I'll put a meter on the SH tonight and see what real world draw is..

So far we have 118 watts when the brake lights are on... The fan will suck up a lot.. but, not likely to be on at the same time AUX lights are running.

My bet is, you'd be safe with 1 Halogen AUX light.. or two HID's Which is what I'm looking at doing.

I use a pair of HID's from a company called TrailTech as helmet light along with an 8" HID as my main race light.. Great combo.


Once I get home, I'll know for sure what the SH uses for power

Prior to picking up sponsorship with KC we used PIAA off road lights with good results.

As for what can ya use,, it's simple math. As soon as I check the actual power use we will have a number to deal with.

Then, you use the assumed number of 280 possible watts of available power,, and do the math for what is extra.

Few things to consider.

Wiring harness, connections, battery condition all play into wither the stator can actually get the power to the system.. add in a regulator that is know to fail when used at the max capacity (like a failing battery, one that is allow to discharge, and be charged with the bikes stator, and not a charger) or, if you were to use the bike a fair amount while taxing the charging system to full capacity.. Like, say,, standard running needs plus heated vest and gloves, or Aux lights, ect ect,... While I have no firm numbers on what can be used safely.. I'd make an educated guess based on what I know, and what I have learned about the SH, ,,and say,, you should shoot for no more then 80% capacity. That is of course just a WAG.

80% would make the target number 224 watts

*THIS IS A WAG*
