SOURCE: battery location for a 2004 suzuki intruder 800

Hi ...... Find where the battery is, under the seat or behind a side panel. Disconnect the black (negative lead usually with a 10mm spanner then disconect the red (positive) lead. The battery will be held in place with a 'rubber' strap or a bracket and depending on type of battery there may be a vent hose from the battery to the lower half of the bike, this just pulls off and remains in place until you replace the battery. Installation is reverse except you connect red (positive) first.
Let us know how you get on.

SOURCE: my battery wont keep a charge

did you check the rectifier circuit? thats the only thing left in the charging system can check this buy using a voltmeter, first gain access to battery.... ground the black meter lead to a good frame ground (make sure bare metal surface, not painted), and touch the red lead to the positive terminal on the battery..with the engine at idle, you'll probably see about 12.5v or > increase to 4000rpm and watch to see the voltage rise to approx. 13.5v to 14v and then while holding it at this rpm you should see the voltage being rectified down to about 13v, release throttle now, this is normal operation rectifier is working. If the battery still wont hold a charge then the negative battery cable is probably shorting out on the frame somewhere and draining the battery. You can try to see if this is shorting out by driving the bike around (if you can), for at least 15 minutes above 4000rpm then take a voltage reading real quick... it'll probably be around 12.6 or> ..13v is excellent. now disconnect the negative cable.. tie it off so it wont touch anything, and leave over night next day it should still read about 12.6v. Hope you find the trouble. Can you let me know if this helped you a lot.

SOURCE: Boulevard C90 Having trouble w/keeping battery charged.

to determine that, you will need a voltmeter and a battery charger. first, put battery on level surface and check to see if the acid is at a good level, if not, you will have to get some at a parts store and refill it to level indicated on the side. fully charge the battery over night with the charger taking the battery out first. the next day, disconnect charger and write down voltage obtained from voltmeter. next, install battery on motorcycle and try to start it. if it's starts, use voltmeter to check voltage at battery while running engine, write it down. let it run a few minutes like 20 and shut it off. check voltage, if it droped, your alternator is not charging. if it's the same as when you first tested it at 12 volts, you might be good only if you had to refill it, if not, the battery is defective and must be replaced.

What cause the 2000 800 Maraudar rectifier to burnout

Hi Ken, in order to check out any main system electrical circuit, you have to start with a fully charged battery 12.5 volts or better, and be able to pass a load test if necessary.
1. Check battery terminals for damage or corrosion, check battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
2. Check the voltage drop at the battery when you hit the starter button, anything below 9 volts you might have a faulty battery.
3. Check voltage at the battery with the bike running at 3,600 RPM should be 14.3 to 14.7 volts. If you are not getting these numbers, you might have a faulty voltage regulator.
4. Make sure voltage regulator is grounded and functioning properly, watch the video below on how to test a voltage regulator.
5. Unplug the connector to the alternator and hook your multimeter leads to the alternator (pin/socket selection does not matter) set the multimeter to AC volts, at an idle the meter should read 16 to 20 volts AC. at 2,000 RPM 32 to 40 AC volts, 3,000 RPM 48 to 60 AC volts. If you are not getting these numbers, you may have a faulty rotor, follow step 6
6. Set the multimeter to OHM'S, connect one lead to the alternator (any pin/socket) and the other to a ground, the meter should read infinity. Connect both leads to the alternator meter should read 0.1 to 0.2 OHM'S. If you are not getting these numbers, you have a bad stator.
7. Check all wiring in the charging circuit for worn or chaffed spots and all wiring connectors in the circuit for corroded, broken, or loose pins/sockets, which is the # 1 offender.
For more information about your issue please visit the websites below. Good luck and have a nice day.

Not charging

check fuse on positive to battery,if not blown the check feed wire from stator plate to regulator should be around 80 to 120 volts ac.
if low voltage then you will need a new stator/ 999pounds 50cc lifan on the road 3yr warranty

Brand new battery dosent stay charged. charge battery and bike runs fine....then battery goes dead...charge battery bike runs good but pull a wire off battery and bike dies. Im thinking stator is

You need to check the charging current and also the discharging of the battery in the IDLE mode.
Please check this link for some tips.

Use a multimeter to check the charging current and also discharging rate when the engine is switched off.

The alternator and accessories must be checked.

Battery keeps dying in my Kawasaki 900

possible reg/rec issue or the stator....if you have a multi meter you can check the stator by unplugging and hooking up to the stator (component side), set multi meter to volts a/c and connect each plug for voltage. then do a residence test on the stator.
reg/rec issue, make sure you have proper ground, do a diode test to make sure that it is d/c and not a/c

Replaced stator, brand new battery, died after 10k ride

sounds if regulator is not working or poor connections within charging circuit

I have to jump my bike and when i disconnect the jumper cables by bike dies and i have no power. where do i start to look for the problem

I have a generic answer for you, this is a problem with your charging system, alernator, regulator.
this is a good site for used parts if needed. heres a site for a manual. ><
Now I would start looking for a blown fuse, then wiring to & from the alternator, which will be loacated in one of the side covers, (look for a bundle of wires going in) look at any plugs and the metal conectors inside for hot or cooked wiring. repost what you find.

i would be looking at the voltage regulator,if the regulator is faulty the alternator will not be replacing the voltage that the bike needs to keep running
