A good battery should be holding 13.2V. Test the battery at rest. Charging you should see about 14.5V.

Yes have tested when bike off and it's below 13 v just don't want to get a new battery if it's another problem

[DJ123]

do you have access to another bike/battery to see if the charging system is working ok?

[horsey]

No not really just gone and got a new battery here's hoping it works
