My battery in 1981 suzuki gs 850 g keeps dying on me, I charge it up everytime I come back from a ride,the battery is only a few weeks old,could it be my voltage regulator,or a wire that has some of the casing melted off

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.

check your battery connections.

needs battery to run. dc ignition do not disconnect

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.

you need to have the carburetors completely cleaned.

clean all earth connections and re-try

Ok pal here we go...grab that oil cover and wiggle, pound and pull..it's just stuck..that bolt has an o ring on the other side thats why it doesn't pull out easily....go to a good motorcycle parts store and get a filter and 4 qts of Castrol Syntec Actevo 10-40wt Pour oil into dipstick hole, bike on centerstand on LEVEL ground..pour 2 qts in and chk dipstick then top off slowly...checking stick every 1/4 qt button her up and have a great ride for me....Drain bolt is on bottom of crankcase and is 17 mm in case you didn't know...Good Luck to you friend......Tim

The battery LOOKS new. Your battery is three years old. Batteries age quickly. They normally last 2 to 2-1/2 years. Just get a new battery and ride the bike more frequently. In lieu of that, get a cheap 1amp or 2amp trickle charger and charge the battery for two hours once a week. Be sure to keep water over the plates in each cell.
