Can anybody help me out?

 

Did you charge the new battery before putting it in? New batteries need to be charged too. Check the voltage on the new battery.

If the battery is good check the connections on the harness, especially the headlight since that's a possible symptom. Good connections, check the starter button and kill switch connections. Sometimes the solder breaks loose on there. And make sure the battery connections are properly tightened down as well

 

stator might be dead.....
Should be a test similar to this
