I'm not sure if I have a bad battery or charging system. Should I be able to remove the negative Battery cable with the bike running and it continue to run? Mine dies if I pull the - cable with it running......

Thank You for the help.Comment

So is the bring to 2500 rpm and check for 13+ volts at the battery the correct way to test? I'm new to GS'sComment

That's not "help", it's sound advice ! How about taking a more conservative route to checking your charging system ? Go here ,do the quick test, and report all 6 results(note that you must with fully charged battery)

If you are not seeing an increase in voltage with RPM, then you have an R/R problem, stator issue, or possibly both.'83 GS650G

To be perfectly honest it is a friends bike and he had done the pull - cable before I talked with him. I'm not sure what his thinking was. I told him I would ask so I did. Since then I have walked him through the testing procedures over the phone and the stator failed the ohm resistance test.Comment

To answer your original question, these bikes need at least a semi-working battery in order for the ignition system to work.Comment

That is what I thought. That is why I asked but it turns out his stator was bad anyway. We will be putting a stator in it in the next few days.Comment

He is trying to spend as little as possible. How do we test the R/R? I know allot of people change both at the same time.Comment
