I have an 04 heritage battery checked out fine - no headlights only dash lights and front fender and won't start even with a jump - completely dead. What could it be?

SOURCE: 2007 Dyna won't start. THe headlight won't even

1. check main fuse

2. check battery again

SOURCE: check engine light and battery light

if you do anything you will void the warranty you really should return to dealership

SOURCE: fuel light

Soundsa like computer problem.Hooking up new battery created a fault code.Check for faults an check manual for how to reset.Bet the code says fuel fault and will direct how to reset.Hope that helps.

SOURCE: 2005 heritage softail will not crank. only thing

I have a Harley fatboy and I had the same problem, I found that the switch itself was the problem, I replaced the switch and all is good again

Testimonial: "Thanks. I will test that solution."

I don't know a lot about the electronics on the newer bikes. I work on older stuff but it sounds like the security system has nailed you. That would be my best guess.

Good luck
