[Corbin Lock]

My bike won't start unless I have a jump hooked up to it. I turn the key and the relay just clicks.

I swapped batteries and same problem. Pulled all fuses except ignition, no fix. I took the starter relay in for a check and it was ok. I did the screwdriver to both leads of the relay and no start.

Voltage on battery drops a lot each time I try to start. Checked ground cable and it's tight. I dont know what else to check

I can jump it with a battery pack or another vehicle. It will run fine but there is some sound coming from the alternator.

It looks like theres some marks on the piece on the first picture but im not sure if this is the cause or not?

I tested the leads in the connector to the main harness. It seems all of them are ok. They all had the same ohms reading so I guess that means they're good.
is there anything else in the alternator to take a look at that might help?
would it be worth taking the bike to a shop for diagnosis or would a repair manual help?
