Is it ok or am I asking for trouble if I use jumper cables to jump start my bike, I don't want to fry something in the electrical system but don't know if will be a problem?
Old days - running the other vehicle was a good idea - boosted available voltage from about 10.5 - 11.5 to around 13.8 - 14.2 volts, and if your were jumping another car that had an almost completely discharged battery (say lights left on) it gave a bit of extra ooomph to the dead vehicle, and prevented the good vehicle from having its battery drained.
But alas - in the quest to try and increase mpg, engineers (darn them guys :wink have redesigned the alternators on the newer vehicles to only charge if necessary, and do it in a pulse modulated fashion. Having the engine running whilst jumping another vehicle does not so great things to the sensing circuit and confuses it. This in turn does not so nice things to the various components on the jumped vehicle once it starts, and possibly the running vehicle because of the new electronical type systems.
That's the layman's description - I really have no desire to type a long winded one tonight. Point is, the wing's battery is small, you won't kill the donor vehicle by leaving the engine off, you'll protect everything involved, and still get your bike started.
I have to admit I had a saddlebag lighting issue last year at the Jacksonville IBA ride, and had to get a jump start not once but twice while I was down there. No issues with the jump, just my pride. And I carry cables in my onboard tool bag. Have jumped other bikes also. So the moral is - not a problem to jump start - either as a donor or receiver.
It's best not to chance it and both batteries are small and the donor battery will have good cranking amperage. See the bold sentence in the article above.What about from wing to another, I carry cables just in case. Should one leave the bike running so the other bike does not drain the other bike's battery down.
Before I get into the explanation, look at it this way. A car battery from a car that is not running has an awful lot of current capacity, more than enough to start a dozen motorcycles without affecting its own state of charge by much. There is simply no need for the car to be running. That in itself should be reason enough.i am just curious as to why you guys say dont have car running i know a jump from the battery is like having that battery in your bike but having the car running is just going to charge your battery, unless you hook it up wrong,the alternator puts out the same as bike
I have a battery tender, with a permanent cord but that won't help me if I'm on a trip somewhere, I bought bike jumper cables to use for emergency use only and didn't know if I was going to fry something or not, guess I should have explained it better on my first post, thanks for the replies though. :thumbup:Why not attach a battery tender? I have a permanent cord attached to both my wings. When not in use for longer than a couple weeks, I plug in the battery tender. Then when it's time to start, no issues. One of my bikes is an. '87 Aspencade, which has been known to draw in the battery all the time. If I don't either disconnect the battery or attach a tender for long term non-use, the battery will drain. No idea why either. I have had the best look at it, the late Jim Venne of Venco Wings, who was the best with antiques. He could not determine the problem after tearing the bike apart other than the clock that runs all the time. So I use a battery tender per his advice.
