I've been rebuilding my 09 Mastiff, changed the battery out and had it started. Went to start it and the light came on and then off. Now I don't have any power. Could it be a fuse? Any suggestions.
What year and model of bike. Yes it could be a fuse. Circuit breaker could be tripped. Could be new battery is bad,could be loose battery connection. Could be lots of things. What ehc are you running? Take pictures and post them.
