URGENT: Z400 Won't start
 

Left the key on, battery dead, switched batteries from another Z won't turn on. I can drop start it, I rode it for about 2 hours,, turn it off, won't start up. Nothing.

Also it does weird things. Won't rev up all the way in neutral when lights are off, neutral and reverse lights won't light up when key is turned on, but the lights will show up when key is on the on/ light mode. PLease help any suggestions, i'm taking it to LS utah tommrrow and don't want to drop start it all day long!
