2nd Gen Versys 1000 Alternator output
« on: October 25, 2017, 08:31:09 PM »
I've done some digging on this and other forums and have not been able to determine the rated output of the alternator of my '15 Versys 1000 LT.


My wife has a '17 Vulcan 650 S and I put on my heated gloves and jacket, cranked the thermostats to high  and hooked up a volt meter and took off.  It held steady at 13.8 volts when running and dropped a bit when idle to 13.2. I'm guessing the 1000 should have at least the same or higher watt output.

Has anyone here ridden with lots of heated gear and watched the volt meter?

I also recall that there is perhaps an "upgraded" stator refit for this bike?

Thanks in advance,

This is why I love forums! Thanks so much.

That converts to around 350 watts at 12.2 volts. I think I recall a fuel injected bike needs about 225 watts to operate. That would leave at low RPMs 75 watts to power stuff. This is the theory anyway?

I just did a test and hooked up a Gerbing heated jacket and gloves that draw about 90 watts and started up the bike. At RPM's above 1300 I was getting a good charging voltage of 13.8 volts. If I kicked in the high beam volts dropped to 12.5.  1500 RPM and above the volts are over 14.1 and anything over 13.8 is charging the tiny bike battery. That's not great for when your sitting at idle but then with out the wind you could just turn down the temp on the heated gear. Volts jump up then.  Or you could sit there and pretend your a Harley and blip and rev the throttle. Even just putting it up to 1400 kicked up the volts.

Proof that I can run my heated gear and keep my arthritic bones toasty in the "brutal" North Florida Winter :37:

Replace the headlights with LED bulbs and you will be fine even at idle. I run jacket,pants ,gloves and grips with no issues at all.

That's a "bright" idea. I had a very bad experience with melting my Thunderbird headlight housing with an early LED headlight bulb when it's fan stopped working so have not gone there in years. What was the brand and model of your LED upgrade? Was it plug and play?

I don't remember the exact brand ,I  got them on Amazon for about 50 bucks for the pair....they are plug and play,very bright  and have worked fine for about a year now.

The one thing I did have to do was bend the bulb retainer on the bike a little bit to clear the rear fan on the LED's...but just a slight tweak, nothing major .

Ill see if I can dig up a link....

I know on my V1K Mk1 fitted with a voltmeter I have around 110 spare watts at 4,000 rpm (100 kph) before the system voltage starts dropping below 13V.

I mentioned 13V because if you allow your accessories to load the system so that the voltage drops below 13V you will begin to discharge the battery, use 12V as an accessory base load figure for a long trip and you will find that after stopping you will no longer be able to start the bike (flat battery) as many people have found out the hard way.

I remember from Kawasaki literature that when the MkII was released it had a SLIGHTLY larger alternator output over the MKI.

So it's just heated grips and LED spots.
