    Re: LEDs and current draw

    I know you measured the resistance of your stator, but did you measure the no load voltage output of its three phases? With the R/R disconnected, you should see around 60VAC nominal on all three phases at 3-4K RPM (check your shop manual for specifics). If the reading is low, you either have a stator problem that goes beyond a simple resistance measurement or the magnets in the rotor are weak. There really isn't an accurate way to test the rotor without specialized equipment but if you take off the engine cover to expose it, it should attract a screwdriver with a fairly significant force. Also look for chipped or cracked magnets.

    Re: LEDs and current draw

    wow, this shit is better than the clymer, thanks man!

    here's what happened on today's commute:
    1.) 5-7krpm - grips on low: light solid green!
    2.) 5-7krpm - grips on high: flashing between red and orange

    so I can comfortably use "low" with the stator as-is....so are there ways to maximize the heat that's being used?

    I've seen guys wrap the bars with electrical tape so that the clip ons don't turn into a heat sink...is that effective?

    I can also get some cold weather gloves...right now I'm just running leather, and it gets cold and brittle...

    Yes, insulating the heating elements from any metal is effective.

    Gloves will insulate your hands, both from the elements and from the heaters. So thick gloves may reduce the effectiveness of the grip heaters. In my view, the beauty of the grip heaters is that they let me use summer weight gloves (with their better control feel) later into the fall than I would normally be able to.

    You could also consider trying to add some sort of wind protection for your hands. On ADV styled bikes like my 'strom, this means adding hand guards. 'Zuki makes OE guards that are standard on the DL1000 and bolt right up on my 650. They are cheap plastic and not terribly effective as hand guards for off-roading. But they work great for wind protection. Not sure that would fly for sport bikes.

    There's also Hippo hands if you're serious about keeping warm.

    It turns your grips into ovens

    Re: LEDs and current draw

    huh...forgot all about those...but will keep hands warm without costing electricity....and I can keep my year-round (thinner) leather gloves

    there are generic branded "handlebar mitts" for $20 on fleabay...in for a pair!

    handguards might not fit the fzr...when I turn the bars to park, they already tap the upper fairing...

    awww yeah!!





    ...umm...I think...

    they don't fit very well...feel like they'll blow off at freeway speed...and they cover up the turn signals/run switch a little bit...test run Friday morning...

    Re: LEDs and current draw

    they suck balls...anything past 35mph and the wind pushes them against your clutch/brake levers...a few times I wasn't able to grab the brake in time because the hippo hand got in between

    they would work well if there were some metal handguards (ie. mx barkbusters) to keep space, but I'm going to look into some cold weather gloves instead

    Re: LEDs and current draw

    anyone know where the heating elements are in heated gloves?

    are they on the inside of the hand or outside, or both?

    running heated grips is good (on high), but the outside of my fingers can still get cold

    Re: LEDs and current draw

    Depends on the glove. The firstgear / warm-n-safe gloves that I have put the elements on the outside of the glove. The inside of the glove has a small amount of insulation and no warming (for feel I assume). I think the intention is that the glove work well with grip warmers. I don't have grip warmers, so pads of my fingertips can get chilly, especially after a full season of wear.

    Re: LEDs and current draw

    argh....forget it...I can't run grips & gloves...my bike can barely handle grips

    so I stepped up my "core" insualation...keep the core warm, hopefully circulates warmer blood to the hands (which will still have winter gloves and heat on low)

    picked up one of these for $60:



    it's the nelson riggs "arctic" rain suit - think of what a rain suit is, and add a nylon liner for warmth...super toasty, even for a 138lb 6' monkey like myself

    I think I can pretty much ride anywhere now!

    How much current does it draw?

    ^^I should've put this in my "replacement" FZR600!

    the older FZR's had a poorly designed R/R...which lead to premature failures...I thought it would last because it was new when I got the bike, but it died in 2 weeks

    had I installed that right away, I would've saw it coming...

    95+ R/R installed...SD voltage indicator installed...everything green on test ride
