Today my 06 883 Sportster died. It felt like it was running out of petrol, the lights on the speedo were flickering and the alarm was making short beeps. I turned it off and now it won't start, no lights on the speedo the indicators don't work the headlight doesn't come on, nothing. If I use the fob to turn the alarm on the red light on the speedo flashes but the indicator flash/beep doesn't happen. Has anyone had any experience with this or know whats happening please?

I would start by checking the battery voltage then fuses if that is ok.
