My Bike is a 1994 Virago 750, i used the handlebar lock and little did i know the tail light was on the bike died, i bought a portable jump starter (Anker Roav Jump Starter Pro) i fully charged it and connected to the terminals it read around 15 volts I put th bike in neutral and squeeze the clutch and the starter button doesn't do anything at all it only made like a buzzing noise under the seat cant seem to figure out what it is the fuses seem okay and bike was working beautifully before the battery died can it possibly be the battery?, when i do press the starter button the volts go from 15 to around 11 so the button definitely works please help!

Sounds like the jump starter just isn't providing enough to crank it. That buzzing sound is the starter relay, and turns on, the Voltage drops too far, and it turns off, repeat. It could be the battery in the bike has lost a cell, and is keeping the power too low. Take the battery out of the bike and to a place that sells batteries, like an auto parts store, and have it tested.
BTW, did you find out why the tail lamp stayed on? Your key switch probably has two position that stop the engine, OFF and P; P stands for Park, and leaves the light on.

Hit the starter button and tap on the starter solenoid...
usually clicking/buzzing sound means its low on voltage, but 11 should operate it..

Does your bike have a fuel pump? That makes a buzz and is located under the saddle, plus it would stop running once the carbs are full.

If your alternator is putting out charging voltage and your batteries are going bad it is usually because of corrosion in the wiring connections. Start at the black ground wire attached to the engine block. Remove the wire use a wire brush or light sandpaper and clean the terminals and the area where the connector touches the block. Apply a light coat of spark plug grease on the connection after reinstalling. Check the wire terminal for corrosion in the wire also. Follow that wire back to the next connection and do the same. Do this until you have cleaned all the terminal connections. Then do the same with the red positive wire starting at the starter and alternator. When that is complete check your battery voltage it should be 12.5 to 13 with the engine off. depending on its state of charge. Start the engine and read the battery voltage at the battery again. It should read between 13.5 to 14.3 VDC
If it does not read at least 1 to 1.5 volts higher with the engine at 2-3000 RPM you have a bad alternator or regular. If it reads too high your regular needs replacement. Cleaning the wire and wire terminal connection solves most electrical problem on motorcycles. Cost nothing to do but take a little time. For the plug type connectors get some contact cleaner, spray both male and female allow to dry and plug back together. Good Luck

Then pack that thing with dielectric grease.

Or have we read the same symptoms so many times in other threads it just feels like it. I get confused easily sometimes. Anyway ... keep adding cleaners and grease or just replace the wiring? Seems like replacing the wiring would be a better option at this point with the age of the bike with corrosion possibly deep in some wires. Although it's not terribly old it's still possible that a wire has some deep problems there.
