Dead battery?

Hi.
When i push the horn or flash buttom, the red warning light, with the bike started, tends to lose its luminosity and the bike turning itself off.
The bike is on thevstand from a mounth without the battery (a old one) charching.
Is the battery download?.
Ciao

There is a good chance that your battery is not fully charged. It might be best to fully charge your battery and then see if the
"luminosity" you describe still exists. It is quite easy to read the voltage of a battery using a multi-meter and with it you can
perform some simple diagnostic tests that will tell you if your battery is failing.
