EC 300 2018 starter problem

[eralha]

Good Morning,

Last Sunday the starter of my gasgas ec 300 stopped working, it worked without turning the engine. I dismounted the two covers, the bendix and the ignition to check and it was the bendix that was stuck and did not act.
After lubricating everything I set everything to see if it was ok, I mount it without putting the joints and now the starter does not turn the engine. The battery has 13V is still the original battery.
I give here a video of what it does now, i just orderer a new batery, should i try and make the wire mods?

I need to say that my bike has 70h now that starter allways worked, not 100% but worked when i needed cold and hot.
