Uhhhhh???????
 

Hey guys, I got a Tank Sports Urban 250 DE today... needed a battery..

SO

I put a battery in it, and the headlights came on. Key wasn't even in the ignition.

Also the fuse near the battery got REALLY hot. There is 5 fuses in the fuse box, is there supposed to be 6? I don't know anything about this issue what so ever! Any ideas or help would be greatly appreciated.

sounds like the switch is bad or you have some really bad wiring. What happens when the key us turned. Does it have an alarm with remote start?

I'd say bad key switch too.

So key switch it is then. But why do the fuse holders get so hot they burn?

its shorting to ground and drawing too much current
