Engine stutter and stall with additional electric load - heated jacket

Hello,

Went for a rally ride on my new to me DL1000 K3. The sun had set and I plugged in my jacket (fused connection directly to battery) and intermittently the engine would sputter when I had my gerbings jacket on over 20%. One time, with the jacket at 100%, while going 50+mph, all electric went out- headlight and the engine died. Nothing like bump starting your bike while coasting, at night, on Wisconsin rural roads.

There are no other electric farkles. Connector is direct wired and fused to battery.

Come to think of it, I have encountered some hiccups while cruising but didn't think much of it, now thinking they are related.

I am going to start with testing the battery and charging system with a multimeter.

Bike starts great every time, battery is two years old. I don't think it is the battery though.

Thoughts or other areas to check?

I will be adding heated grips as well for an October trip to the black hills and commuting into December in Minnesota.

Thanks in advance, looking forward to lots of adventures on the Vee... just need to figure this out.

You may have the dreaded loose magnet syndrome.

Normally that load should not be too much. First fix is to unplug one of the headlights so you can get home.

Next install directly to the battery temporarily a digital V-meter with a switch or on switched power, if there is relay box. Monitor the voltage and see if its in the normal range >14V or not. If not search for charging system problems. There are many threads about it here. Just one recent one:

Common problem on early VEE's is that the magnets are not glued down well and move together.

Other potential issue is a shortened stator. Again many threads about that.

First measure to know if your system voltage is normal or not while riding!

A permanent voltmeter is a must have on these bikes.

I too would guess your magnets in the rotor have migrated together. Which can lead to a failed stator.

These bikes have plenty of power to run the accessories you mentioned, but only if the charging system is up to par. These bikes run like crap when the voltage drops!

Update: I ordered a digital volt meter to display when riding. Should be here in two days. I just borrowed a volt meter and the batter cold is registering 13.04 volts on the terminals. It is too late in the evening to do a running test. Will try it tomorrow. Thanks again!

On my 2002 DL1000 with a 3 y/o battery: 12.50V. key OFF; 12.04V. key ON; 14.4V. cold, fast idle with engine running at 2000rpm and charging. Readings were taken with a digital VoltOhmMeter at the battery terminals.

14.4 V. showing on installed volt meter while riding. Usually. Drops into the high 13's for a while sometimes on very hot days.

I've been wondering when these problems really started. All the pictures I've seen of loose magnets were pictures with SIX magnets in the rotor. When I recently opened up my 2002 DL1000, the rotor only had FOUR (bigger) magnets.

Does anybody know when the output of the system was increased and when Suzuki moved to six-magnet rotors? Does anybody know of any reports of problems with older (2002-2003?) four-rotor magnets?

Edited: 'been doing some digging on MSP.
2002 DL1000 Rotor P/N 3210206G00, 4 magnets
2003-2010 DL1000 Rotor P/N 3210206G10, drawn in the fiche as 4 magnets but I suspect it's really 6 magnets
I could not find a parts fiche for 2011-2013 DL1000s
2014+ DL1000A Rotor P/N 3210231J00, no # of magnets drawn

2002 DL 1000 had a unique charging system. Rotor and stator were different. I want to think they were rated at 350, maybe 375 watts of output. Later models were 400 watts. I don't know that I have seen any of the 2002 magnets loose, but I assume they could act the same as later models.

The 2002 DL1000 had a 350W charging system. It went up to 400W in 2003 and 490W in 2014.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

Go here and click on lower right "view poll results":

https://www.stromtrooper.com/informat...r-magnets.html

Note the result for 350watt, DL2002 loose magnets. 0 ZERO, that is.

Things kinda went downhill from there. 400 watt = overbuild? Outsourced parts after 2002? Suzuki got the rotor right, clutch basket wrong in 2002. Funny how things sometimes seem to even out.

@Austin44 - thanks for the numbers! I'll get to dig into it this weekend. It is getting cooler here in MN and I really need to get this sorted sooner than later. The riding season for me typically goes until they start laying down salt...
