crowley1027 Test the junction box, double check for exposed wires (particularly by the left side neck), check fuses, ensure good ground (triple check all three grounds [right side battery box mounting bolt to rear bolt on engine, frame to negative, and harness to frame])

Goofyfoot2001 I'll just say again then that these starters are pretty solid so probably not the starter. There isn't much to a starter anyway. Cars have more starter problems because mechanics like to sell them.

Sock The OP has already done most everything except rewire his bike and tear the engine back down. https://www.vn750.com/forum/showthread.php?t=72426

Goofyfoot2001 You can run a wire directly from the starter to the batter and see if it spins. Don't take the starter off with oil in the bike though.

Spockster Could be a defective starter, that's a huge drop from 12.97v down to 6v, that starter is drawing amps HARD.

Sock Don't take that about a clutch as gospel until someone else chimes in, I'm making assumptions based on the parts diagram.

Uh oh. All sorts of bad things happen when you let the smoke out. Something is making that circuit overload, and the quickest way to do that is with something binding the starter motor.

I haven't had mine apart, but looking at the parts diagram, there's a one way clutch between the starter and crank gear. Meaning the starter will turn the engine, but the engine won't turn the starter. If it does indeed work like that, you could turn the crank by hand but if the binding is on the starter side you wouldn't know.

Spencer1 At 12.97v your battery is fully charged. Solenoids generally don't smoke since they are basically just an electromagnet that makes a connection. I'd suspect the brushes in your starter or the engine may be locked up.
