Suzuki GS750 won't hold a charge - GS 750 E Suzuki Motorcycles

SOURCE: Battery on 125cc Suzuki GS is ok- but not being charged

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

Either has a charging rotor problem, stator problem, or regulator rectifier problem. Get a manual and trouble shoot.

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.

Have you checked the points? Be sure to clean the point contacts, also she may need a new condenser if it is not new (they break down with age). Did you clean the carbs? Did you mess with any adjustment screws? post back with what things you have done.

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.
