Motorcycle Questions? Ask a Mechanic.
Hi George and welcome to JustAnswer,
Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, it would appear to still be a battery issue as the battrery is not expected to go below 10~11 Volts.
Proposed preliminary tries (if have not been done) would be to re-inspect the battery, its ground lines and/or check/clean the battery cables + terminals, connectors and wiring as a preliminary consideration.
Have the battery externally charged and then LOAD TESTed (even if charged and just for the purpose of eliminating it as a suspect).
Yes please George; when able.
And strongly consider LOAD TEST for the battery. It would be the best test and confirm if the battery is still good or would need replacement.
