Charging system
Question Today was day three of having my 83GS750ES on the road. But when i went to leave work i had a dead battery. I compression started it to get it home. 55 lovely miles. But when i got home the battery was still dead. It's not getting charged. SO where is a good place to start in the diagnostics. Is there a common issue with these things. And what are some you guys running for sprockets on these, this thing is so low geared it unreal. When i am doing 60 mph im turning 4000rpm. I think that is a little high myself. But i could be wrong. Can anyone point me in the right direction to get started. I need to get this thing back on the road it's my daily means of transportation right now. ThanksTags: None

Diagnosis:
Start the engine (err well push-start it ), connect a voltmeter at the right range to the battery + and -. Turn the throttle to 3000-4000 rpm. The voltage should now rise from 12 to about 14 V. If it does this, then your battery is dead. Replace.
If it doesn't do this, then check (measure on meters' resistance-position) the wiring to- and from the regulator/ rectifier with the engine off. This is the alu thing with the cooling ribs attached to it (no, not the engine). If everything is wired OK, replace the regulator/ rectifier. It's a common defect on Gs's.
Good luck, Marco.

Not sure about the sprocket size but you do need to check out the Stator Papers. Go to the homepage and click on 'In the Garage', then click on 'The Stator Papers'. There is a wealth of information in those that will help you diagnose your charging problems. If it were up to me I would just get an Electrex stator and regulator/rectifier, kinda like getting a midas muffler and putting all your troubles behind you.
