You need to have stator coil tested.
An alternate problem could be the regulator/rectifier.
Both of these should tbe checked by a dealer

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.

Bike won't start. the starter won't roll over

The basics first. Check that the battery is charged, fuses are ok to include the ignition solenoid fuse. Should be a 30A. (Usually near the battery) Next starter button tests ok, then check starter solenoid. Hope this helps

You have a battery that has a bad cell maybe, or you may have a short to ground thst is depleting your battery. Charge your battery and disconnect the pos lead and check the battery charge daily. if it falls more than 2 volts over 5 days you have a bad cell and you are probably looking at a new battery. Take a look at the fluid level in each cell. Fluid level that uncovers the plates may be the problem. You have to check the level at least once a month unless you have a maintenance free battery.

Charging the battery

Turn off ignition. Disconnect battery terminal leads, ensure fluid levels are ok, connect charger leads. It is best if you remove battery so you can give it a clean and save your bike if something is amiss somewhere and it erupts or leaks when charging. Try the sites below for manuals or go to Wiki Q & A under S40 Boulevard, then wade thru' for links.

1978 GS 750 E: battery will not charge...

if it takes a charge off the bike on the bench, (if not replace it) check your fuses.If you still cant run it, the volt regulator (rectifier) may be bad.

I have a 1980 suzuki 850 gs and its not charging the battery properly what should i do and where is the charging system located on the engine

As suggested, check the voltage with the engine running accross the battery. If its below 14 volts you have an issue with the stator windings/regulator/rectifier/wiring.
Do the cheapest thing first and clean up all electrical connections, esp the earths.
A manual will tell you how to test the charging system, but the Suzuki GS range has always had charging issues.
The simplist method is to fit the combined reg/rectifier unit from a Honda CB250/400 Superdream.
Always keep your engine oil topped to the max mark, as this cools the stator.
Dont leave this, it is not unknown for the entire system to fail including the CDI if left unchecked.

Can I use a regular trickle charger on a GS650 or is there a special bmw charger I need to buy. It's my buddy's bike and I hadn't started it for 23 weeks, now the battery is dead

You can buy a BMW charger if you want to spend some bucks that you don't need ;-)

The "brand name" BMW charger is the same as a C-TEK charger, they say it conditions the battery so you can leave it on charge permanently and it won't damage it. However, the cheaper models you get at Wal-Mart or similar only consist of a transformer, rectifier and some Zeners, maybe one or two IC's. This means you can leave the battery on for only about 2 days max otherwise it starts to sulphate and it slowly damages the battery.

I suggest you check the battery water levl, the connect a regular trickle charger to boost it. If you use it wizely it will be fine.

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.

  • Battery 2 or more years old? It may need to be replaced.
  • Before charging, did you add water to fill each battery cell to nearly full? Distilled water works best.
  • Did you use a 1amp or a 2amp charger or did you use a larger amperage charger? 1 or 2 amp is what you want.
  • Is the charging system on the bike still working properly? Put a voltmeter on the battery and rev the engine. The meter should register 14+ volts.
Please rate this solution. Thanks!
