07 bandit 1250 2 batteries in 3 weeks

Help, please, I need a little knowledge here.... i just went to start my bike, and i turned the key and i got no power. battery is 3 weeks old and is reading only. 1.4 volts dc. i know its not 14, but 1.4. its now charging.

Same thing happened with a two year old gel battery 3 weeks ago. I assumed the battery was dead so I bought the agm battery that is currently charging.

The bike ran fine on Monday. Now 5 days later its down to practically nothing.

What can cause a battery to run down so low just sitting in a garage for 5 days?

Would anything cause the reading of 1.5 volts other than a defective battery?

Double check your meter, its probably not wrong, but low hanging fruit and all that. Disconnect the battery and charge that independent of the bike. When it's reading 12v, load test to be sure its good. If the battery is sat, reconnect the battery positive and put an ammeter between the negative and the battery. If it shows current, start disconnecting systems or pull fuses one at a time until you find the drain.

Thanks the meter is good i tested my car battery and its at 12.8v. the battery is charging now and at just over 9 volts. I tested the negative wire that has been disconnected and the positive terminal that is connected and its reading 0.00mv, so it looks like there is no draw. I'll wait until the battery is fully charged and test it again like you said and also test the charging system with the bike running.

thanks

What meter are you using? Current is measured in Amps, not volts. Most handheld multimeters have separate inputs for V+ and A+, in addition to being on the correct scale, you've got to have the leads plugged in to the right jacks and be connected to the system in series (one lead to the - wire, the other lead to the - terminal at the battery. Another thing to check is the fuse in your meter - the shunt that is used for measuring current is protected by a fuse.

Your reading of 0mv has me wondering if you've got the system connected wrong. The ECU will draw a couple mA o maintain itself, you should see at least that on the meter.

Lemme go check that... i did not have it set up for amps...

OK... i just tested the bike for current like you said... I got 0.0A. Then I tested a household 9v battery, still got 0.0A. Should have gotten around 5.5A, right?

The multimeter fuse looks good.

Here's a pic if the dial setting... And where the plugs are...


What am I doing wrong??

You've got continuity through the fuse? Yes, you should have seen ~5.5A, connected to just a 9v battery. Everything in the photos looks like you've got it set right, I'm not sure what's up with the meter if everything checks out.

Yes the fuse looks ok... but obviously something with the meter is not working right.... ugh.

Thanks for the help. I'll let the battery charge overnight and try to get a different multimeter tomorrow.

With the meter leads plugged into the volts/ohm holes, simply put the positive lead into the ammeter hole. Should have continuity. No continuity (open, or o/l) means the fuse is toast. Trying to measure voltage with the meter leads in the ammeter positions will fry the fuse.

As for the battery, two batteries going dead means either there IS a draw or the charging system is toast. Measure the battery voltage with the bike off, then start it. Voltage should be at least .5 volts OVER static voltage, preferably north of 14vdc, and less than 14.5. Anymore than 15 and you're overcharging, which is as detrimental to battery health as undercharging.

Pull the fuse and check it with the meter - the current and resistance circuits are typically separate.

the fuse tests at 18.8 ohms.

it connects to a circuit board... maybe there's a bad solder joint in there somewhere.

It's soldered to e circuit board? Weird.

Okay, finish charging the battery and check the charging system as motomedic suggested. I look for shorts first because they're easy to rule out or verify, but a questionable meter makes that task much tougher.

Thanks for the info Moto and Medic... when I do get a AmpMeter that works, what is the max drain or draw allowable?

the cradle the fuse sits in is soldered to the circuit board.
