1993 XV1100 need more AMPS for led light bar

Post by johnxb351 » Sat Oct 12, 2019 2:43 pm

Hi All I just put a 70 watts LED light bar on my 1993 xv1100 but its not all that much better so i would like to go up to about 100 watts but i think 70 watts is about all the charge system handle. So is there a after market Stator to put out more AMPS

G'day mate :D

Could you post a picture of your light bar? My understanding is that LED lights should be brighter with lower amps than regular lights, though I think ViragoJoe is a bit of an expert on this subject. So watch this space and I'm sure you'll get the best advice on the internet right here.

Good to see more Aussies here. I'm Western Australia.

G'DAY Michelle i dont know how to put up a pic sorry.. its a 12 inch or 300mm long . i have put it just below the head light. from what i have read and see most use 2x35watts lights =70 watts so i have just used 1x70 watts LED bar . if you want a pic for your own LED light project i could send by phone. the reason i want better light is Kangaroos are all over where i ride at night

Hi John,
Since we don't know what other accessories you may have on your virago. That may be eating up limited electrical resources. Here's what we do know. You are limited to about 280 watts or 23 Amps total for an XV1100 charging system. Add up the current draw of all your electrical items including all incandescent light bulbs and see how much of a current draw you are placing on the system in regard to the 280 watts / 23 amps available. Then you will know what you have left for other accessories.

As for an after market Stator to putout more power. Am not sure that is available. I suggest that taking a few deep dives into the internet may be fruitful. I myself have not come across anything. However, if you do, please let us know. We all would appreciate more power for these current anemic changing systems Yamaha has designed.

Read this article on Virago Charging Systems:
https://www.viragohelp.com/virago-charging-systems/
Hope this helps you understand our current power dilemma. Yamaha pretty much designed the system with enough power to run the bike with lighting and power enough to charge the battery. Limiting any add on accessories. Bummer!

G'DAY Joe the only other power draw is the 60 watts headlight think about 5 watts for tail light. So say i used 120 watts LED light bar + the 60 watts head light =180 watts total. - 180 watts from the xv1100 280 watts out put leaves me a 100 watts to spare. but as the info in the link you put up says that the 280 watts is when engine is at 5000 rpm when my cruising speed is 100 kph or 60 mph at about 3000 rpm. So watts at 3000rpm is the great unknown

Yes, that would be the great unknown. Unless, you place an Amp meter in line. But, would that be worth doing is the question. For me, it would not be worth it. Like I mention earlier, Virago charging systems are very limited at best. I would say Virago's aren't the only motorcycle's plagued with this same short fall with a limited electrical supply burden.

Another unknown, is how much energy is taken up by the ignition system to run the bike. I don't know that either as has the article outlined. I just don't go with items that I think would over tax the charging system. You will always need to have a surplus of 3 amps (36 watts) available over your totally requirements to keep the battery charged. That's one way to know if you have exceeded the system is when your battery keeps going dead as you ride on into the sun set. :shock: :oops:

The issue we have is a one to one relation ship. One revolution of the crank shaft is one revolution of the Stator. In cars that is changed through pulley diameters and can turn the Alternator several times to the engines crank shaft turning once.

Trivia:
Here's another phenomenon to ponder. Just trivia, how many times does your Spark Plug fire on one complete cycle of a 4 cycle motorcycle engine or any small 4 cycle engine that depends on a flywheel for electrical power. Would you believe twice?! One occurrence of that double spark is considered or called wasted Spark.

Trust Me Here, any time we do something to our Virago's there are always consequences!!

Hi Joe i just read your link did you using lower watts led light then the standard watts lights. if i was to use the LED lights with the same watts as the standard it should draw off the same power to keep the r/r cool. buy the way is there cooler spot you may have found for r/r

Hi John,

I've been looking for a cooler place for a long time, any ideas?!! Remember it needs a good chuck of metal to help dissipate some of that excessive heat. That's why the Yamaha Engineers picked the Left Passenger Rear Peg Bracket. Or maybe a cooling fan mounted to it somehow. Really no room where it is right now.

If you have a touch less infrared thermometer, you will be surprised how much the heat at the R/R fluctuates.
