When I turn the ignition it squeals and I hear a rumbling sound in the lower left Ignition casing (Ignition Advancement Mechanism). Forgive me, my automotive knowledge is limited. It will turn over but I have to try it a few times before it starts up. When I am on low idle I can hear the rumbling in the left casing but is fine if I idle up. Any thoughts?
I have just purchased a brand new battery as well!
 
Is there any visible damage to the crankcase cover - dents, scratches, etc.
If the bike has fallen on that side, the cover will become misaligned and the stator and rotor can make contact - making noise and creating charging problems.
Remove the cover and inspect everything.
Don't worry - there's no oil inside the cover.
Replace all damaged parts, including the cover if necessary.
