Your generator is on the left as you sit on the bike. The GS/gsx Suzukis do have issues with charging the battery.
1. Charge the battery.
2. Use a multimeter/voltmeter across the battery, do you get 13.5volts dc or more? You may need to rev the bike to 2-3000 revs.
3. If the meter just shows battery voltage, you need to check the regulator/rectifier unit. This will be under the side panel (usually left side) and will be a square metal unit with cooling fins. Check all the connections are clean and rust free, ncluding all the earth connections. Test your charging again.
4. If its still not charging, trace the 3 wires that come from your alternator and connect to your regulator. Disconnect them and use a meter to check between each of the 3 wires. You should get 60-90 volts AC. If not, you need new alternator windings. If you get the correct reading, you need a new regulator rectifier unit.

How do i replace battery in 1980 suzuki 850 gs?


Do you know where it is located?
Have you had issues with it, as in dead and let to freeze, acid spilled out onto the bike from being frozen or overcharged etc?
If so mix up some baking soda and water and pour over connections and frame then wash off bike before swapping battery.
Take off negative first and put back on last, just like with a car battery.
If wet cell, fill to proper level and charge first on 1A or smaller charger for a day... If GSM or Gel, install and ride.

Start the bike and put a voltmeter across the battery; you should get a reading of probably around 13.5V. If you're getting only about 12V or less, the battery isn't charging. From there you will need to go to the alternator terminal on the regulator and see if you're getting more than 12V. If you are, the regulator is probably bad, if not it could be a bad rectifier if there is a seperate rectifier or a bad stator. Good luck and safe riding.

Is Idle adjustment important when it comes to charging the battery on a 1998 Suzuki Intruder VL1500? I do seem to have a problem and I find myself having to place a trickle charger on it every once in a...


No, idle adjustment isn't the important thing. Amount of riding and amount of time parked is the thing. If you don't ride much, and it is parked for long lengths of time between rides, you will have a lower battery condition.

However, if you ride a lot and it doesn't get parked for long periods of time, you may want to charge the battery fully then put load test on it to check for one or more dead cells in the battery.

If the battery is not the problem, then you will need to check your charging system.

03 Suzuki GSXR 750 keeps shutting off while I am riding?? HELP!


Seems you are running entirely off your battery.
Indications are a suspect lighting or source coil is shorting. Resistance test will show discrepancies. Data is available on-line, search technical/electrical manuals from Clymer or Haynes. An auto shop sells cheap multi-meters than you can use. It is a stationary test and will identify individual component problems. As rectifier/regulator, cdi box and wiring/switches/connections all have an effect. These test are outlined within these publications. Cheers (and don't get caught)

Wont charge


Hi and welcome to FixYa,

For an 81, a lot to check. The charging system is not a simple affair. You would need to check the wiring, output of the stator and of course, the rectifier / regulator combo among others. Start with the terminals / connectors of the stator to the regulator.

A wiring diagram would help.

Bike shuts off???


if when your bike gets to riding temp. and, you turn it off; and, then restart... if the crank speed is slow replace your battery if your crank speed is normal replace your ignition module (batteries can be recharged and, measure 12 volts and, still be weak)
Amps can fall off (amps are what give the battery muscle to spin your starter ) ignition modules can be affected by heat and fail to maintain spark

Battery not holding a charge,


Check the charging rate of your bike, see if its system is charging, if it does charge thn theres somewhere the battery is getting drained out.
In order to see if tht is happenning, switch off everything and thn remove one battery wire on the battery, after doing so try to fix it back and notice if theres any sparks when it comes to the contact of the battery terminal , if so thn theres a drain somewhere in the electricals and wiring.

Good luck.
