I assume I could use it even if the on board chargers fail? Can I use it on the FX and DSR? Can it be used in conjunction with the onboard charger on both bikes?
I've never seen one in use and not completely sure how it works. Anyone have any experience with them?
Yes, I own seven (yeah, 7) of them. I carried two with me today (one in each saddlebag) to speed up the charging between Auburn, CA and Reno, NV. My SR with power tank can make the trip on a single charge if I ride slow, but I still get range anxiety. If you do this, more cables will be needed. Not needed to use the QC at home.
Yes, always use all the chargers you have up to the limit of 1C (same as battery capacity KWH). But you did not mention the year of your bikes.
See here.At first, You will get a red fast flashing alarm light on the dash if you only run the QC and then it will not charge. Don't panic!!! But if you turn the bike's key on and then off (so the contactor will close) then you can charge with ONLY the Q-charger and the alarm will clear and charge normally.
If you're also using a working on-board charger, you do NOt have to mess with the key.
On the Q-Charger, look for the top light on it to light up to know you are fully charging. That will take a few seconds, perhaps 5 seconds or so after every thing is ready to work.
Bottom line is yes, it will work, with or without the on-board. Just remember to turn the bike on and off after the QC is first connected if you're not using the on-board.
