Hey all.

Was hoping you might be able to help me out? My motorbike shows no sign of power. Turning the ignition turns does not turn on any of the electronic display or the lights. The battery is fully charged. It makes an odd buzzing noise. Any help would be greatly apreciated as I am at a complete loss as to what's causing this. Cheers.

While many of us have or had motorcycles, this is a bicycle forum. Good luck finding help, but you might want to ask someplace like Adventure Rider in the Road Warriors forum or one of the The Garage threads. Lots of helpful folks there.

Sorry! I had two tabs open and signed up on the wrong forum! Thanks for the reply lol

You got the wrong bike forum.

But anyway i suspect you have a ground issue.
Wipe the battery terminals with some sandpaper to clean them and inside the positive and negative clamps. (this will solve issues at the battery terminals if any), then check all the ground cables. It's highly unlikely that the positive is toast since the positive is branched so you would lose some components but not all of them.

Anyway check with a multi-meter to see how far you got voltage (especially check continuity between negative and engine block). Maybe you figure it out - somewhere a major discontinuity is present.

Yeah I'm on the wrong website I had two 'Bike' tabs open and signed up on the wrong one, sorry! Amazing, great suggestion. Thanks for the advice, I will try checking all the wires/ground cable connections and check & clean the battery terminals. Thanks again! Will let you know how it goes.

Sometimes just unmating/remating connections, especially those tab types, will clean them enough to restore the flow of power. Also, make certain that the battery is putting out voltage; sometimes they will fail by having an internal connection going open=no juice... Have you checked any fuses for continuity? Is the ignition switch putting out power? Is there a second (anti-theft) switch which has gotten moved? Have any repairs/changes been made recently, that is since it last ran?
Maybe you should use "moto" and "velo" instead of "bike" for your tabs to avoid confusion. But welcome to the forum.

sorry dsbratjr but checking fuses is pointless here because fuses are on the positive side.

Follow the sound under the fairing there should be the issue with a ground loose. Also check the kickstand - many kickstands have a switch under them to not let you start the engine while the kickstand is out (but it will have had power.. the switch is for the ignition/fuel pump only.. so no dice)
If you have a multimeter is very easy to identify the problem since a loose ground that is buzzing will get some voltage trough so check at somewhere easy like the fuel pump voltage and see if it gets any voltage at all. I suspect there may be some 2-3V if the ground is buzzing and loose. So there are all indications for loose ground somewhere.
I am a biker as well
Trust me i'm an engineer (no really.. automotive engineer)

Thanks very much .

Hey all. Thank you for the replys and advice. I decided to order a new battery as when I hooked it up to my external battery power and charged it to full it did not seem to keep the charge for long at all. Turns out I just needed a new battery! Thanks again for all your suggestions and help

Nice that you got it figure out. A multi-meter would have cleared that out sooner, but it's good that you finally got it.
That battery then was shorting out or something.. weird buzzing
Usually a worn battery has low capacity and high internal resistance.. so it has 12V, powers some leds and dash and may even have some dim lights, but when cranking it dies. A good indication for good battery is to hook a multi-meter for the battery terminals and disconnect the spark or the fuel pump and crank it several seconds. The voltage should not drop below 10.5V while cranking (on a motorcycle with the tiny starter I'd say even 11.5V)

Here's a link to a great fault finding guide for your charging system. Check the "Fault finding guide" and "Diode Testing Guide" links. Check your Stator and Regulator/Rectifier as suggested in the Guide or you may end up with another drained battery or a ruined one. Diagnosis Center - Helping you Find the Problem - ElectroSport
