I have a 99 sportster 1200 with hyper charger,
Lately I can't even take the bike out because it keeps dieing on me.
It gets to a certain rpm/vibration and the speedo flashes and the lights for neutral and to light up the speedo turn off. The bike doesn't turn off but you can't give it gas.
In a nut shell, at a certain vibration all the lights on the bike go out, the bike stays running, I coast to a stop and shake the battery a bit and the lights turn back on and I can give it gas. Please someone help me. I can provide pictures.
Check the battery terminals they are loose
Hello mate
Yes make sure the batt terminals are shiny and nice and tight. Also check the neg terminal where it bolts to the frame. Check the main feed from the batt to the circuit breakers for chafing and cuts. The handlebars have an earth wire going from the risers to the triple trees try that too
