    Anyone know what the output on a 950 05 alt is? I need more gadgets to make my gs friends a little more pissed than already are. Im running an xm radio off a 12v plug. Want some big nasty lights mounted on my new crashbars (recently tested and highly recomended). Any suggestions?:rofl

    Run your electrical clothing Powerlet through a 15A relay's NC contact. Actuate the relay from your neutral light.

    The 50 to 100W 'lectrics draw is taken offline when you need it the least and your charging system is in the most compromised position to support it.

    I wired Paul Taylor's Iron Butt winning GS like this.

    Okay, now that sounds like a smart idea. : thumb
    You know, the kind of thing any of us would have thought of if we were as smart as we like to think we are. :huh

    I connected my Gerbing power outlet directly to the braided leads coming from the battery terminal to the access panel lid. I was able to disconnect the leads and screw the eye terminals underneath the braided wires. Works slick and I didn’t have to interrupt the power to the rest of the motorcycle. I then routed the lead on the left side up the little compartment between the tanks. This allows me to connect an extension cable to the power outlet and close the lid as well. Plus I connect my batter charger to the power outlet and this keeps my battery fresh.

    Can someone confirm that the total output for the 950 is only 450W. I find that hard to believe since my DRZ400 is said to boast a 500W alternator and the BMW GS a 650W. If it is 450W what is the remaining spare watage after you take into account running the engine and lights etc? Anybody here drain their battery due to running an electric vest, hangrips and say a set of fog lights?

    450W is more than enough I'm sure. My KLR has on 280W and I run heated grips and a heated vest no problem.

    Measure the Amperage whit all electronics on.
    devide 450W tru 13V and u know whats left on amps....

    Example: 450W devide tru 13V = +/- 34amps max

    so if your bike pulls about 25Amp, youve got 9amp spare (=9X13=117Watt spare) for example......:deal

    Beaware when you sucking the electricity to the max, it will result in a Big ballast to your altenator and rectifier/ diods enz.....
    resulting over a long time......meltdown:huh

    I run my Aux light 100% of the time, and I have used my Gerbings heated vest and gloves all winter long. I ride and average of 75+ miles each day to work and haven’t had a single glitch with the electrical system, even when I have to turn the temp up on my vest to over come the frigid 20+ deg. Days. The battery stays strong.

    Since the KTM is carbureted, there is significantly less draw for the ecm, injectors/pump. I have a DRZ 400 and it doesn't put out anywhere near 500w??? The 450w should be ample. I have a Guzzi Quota and it is only 350w at 4,000rpm. I can run elec clothing, but I don't play with aux lighting...
    I am purchasing a friends 04 950S and putting a sidecar on the Quota...

    Ive got a set if PIAA fogs and it seems that if I dont maintain a sufficent speed I loose the charge to my battery. I am talking slow speeds here. 10-20 mph. Fortunate for me I was with a friend and with a slight downhill and a little traction it turned over. Lucky as we were way out there on a closed to motorcyles road. ATVs OK but no bikes! Who comes up with this shit!

    does the SE have the same alternator and therefore also have 450 watts?
    thx

    I'd be surprised if it was even putting out half that - where did you get this figure? I would go and dig out the Clymer manual for my DRZ, but I can't be arsed.....
    450 watts is ample for running heated grips, vest, etc. If you've got loads of gear installed then it would be a good idea to fit a voltmeter and switch things off for low speed work.
    I've got a 5 pin relay waiting to be fitted into the feed for my accesory fuse block - the neutral cut-off isn't too difficult to wire if you've got a wiring diagram for the bike.

    I'd be interested to know the numbers for the 990 if anyone has them.

    I have the VStrom 1000 that apparently puts out 480w which is not enough by any means. Means I can only run fogs and a vest, no heated grips. Then when you start adding GPS, intercom, radio. I had to practically replace most of my lights with LEDs (bar the driving lights) to save a couple of watts here and there.

    I'd be surprised if the 990 only has 450 considering the GSA has a 750w alternator or something.

    990 is the same as the 950.
    I'd allow 100w for hi/lo beam, 100w for other lights, fuel pump, Fi, etc, plus 100w for a pair of fogs, 40w for vest, 40w for grips, 20w for GPS,radio etc gives 400w in total. What else do you need?

    I ran my 950 with carb heaters (60w), heated vest, grips and GPS without a problem.

    As others have noted, output is 450W for the 950 and 990. It's listed under tech specs in the owner's manual.

    Page 95 in the '08 990 Adv manual, available at KTM's site:

    More like 200W and that's on a good day.
