    Default Electrical Help?

    Since the FJR was in the shop, I was going to take the CBR into work for National Ride to Work day. I had a premonition it would not start in the morning so I went out last night and checked tires, unhooked the battery tender that's always on it, turned the key to make sure everything lit up and whirred like it's supposed to. It did and all looked good.

    Get suited up this morning, back the bike out, turn the key and everything lit up like it's supposed to.... for a nano second and then a barely audible "snap" and everything is dead. No power to anything. Push the bike back in, hook up the tender to see if the battery has gone bad and it shows the batt to be fully charged.

    Come home tonight and check all the fuses, including both main fuses and all is OK there. Hmmm.... I'm a bit stumped. Tried the wires under the ignition switch, nothing blinked or looked loose. Man, I hope it's not the 'puter.

    Anyone have anything else I should be looking at? Maybe a similar experience and know something to look at I'm missing?

    At first it thought it wasn't going to actually go out on the road like a real bike that see's loving. That's when it fired up. Then when it found it out it was actually going to go out for a ride, it got scared.

    Seriously though, it's probably the battery. My 636 showed the same signs and also showed a good charge on the tender. It didn't set up quite as long as your CBR either.

    I would, but there is absolutely no juice. Turn the key and it's like there is no battery connected.

    As for the battery, heat can't be the issue, the bike sits in the garage all the time on a tender. The battery is a year old. Even if the battery went bad there should be enough charge to get an idiot light to come on.

    That said, it might be the battery. I'll get it checked. Any other idea's.... other than trading it in?

    It's cursed, or more likely a dead cell in the battery

    The snap is a common sound when something electrical is unhappy. Worse is the phoomp, followed by smoke and the smell of burning hair.

    Try disconnecting the positive lead from the battery. Wait. Then reconnect. If still dead, have the battery checked--but likely some component gave up the ghost and it is shop time.

    Disconnected leads when checking the fuses. Still completely dead.

    Gary ... There are two fuses right by the battery and two that look like are in the tail section. Which ones did you check?

    I checked all fuses including both main fuses, as per the owners manual. I don't think this Honda has any fuses in the tail.

    I still think it's the battery. Try this: get some jumper cables and use your truck. Don't start the truck though, just the battery should be more than enough juice. If you start the truck, the charging system could send way more amps through the bike's wiring system than it can handle and you could possibly fry some components. Doing this will eliminate/confirm the battery.

    Did you take the battery out or disconnect it?

    Angry

    As you may remember I had starting issues back in december. Bike would crank, yet no fire. 2 different shops couldn't quite figure it out.
    My computer was put on a similar bike: it fired right up.

    Changed the wiring harness; seemed to work, but after a couple of rides, it was not starting. (but did crank over)
    Battery read 14 volts, yet it died soon after.

    New battery resolved the problem.

    Both shops said one of the sensors was showing a high threshold before triggering,
    probibly why it would crank, yet not fire.
    The old battery had enough juice to turn over the motor, but none left to trigger the ignition.

    That's risky. Jump off another bike.

    Not if he doesn't start the truck. The bike will only use what amps it needs.

    You can bring the battery to an Autozone to have it load tested for free.

    btw- Don't skimp with a POS Cycle Gear battery . I've had good success with getting the dealer to match price for an OEM replacement. They'll last much longer on a tender. ..or get a Shorai and be done with the tender.

    I still think it's a fuse or fusible link or cables not tight. For all to go out with a poping noise. It's not just battery. But thats my .

    Not sold on the battery either. Going to try the jump start tonight. Hopeful, but a bit doubtful. I'm thinking along the lines of Bryan, with everything going dead with a pop. I don't think it's a fuse though.

    Default Hmm

    Check your voltage "12 volts"....fuse must be checked with a meter not just visualy..o and if there is a starter relay it must be proven as well....just sayin ...

    a "Snap" usualy means an arc. Could be a fuse or it could be a loose connection. The only way I know to find this is with a multi meter. Either check for voltage across fuses and connections or test continuity.
