X-Aviation c172 Alternator

[IFRChris]

I have an aircraft that I have bought from X-Aviation. It is the c172 with dual G5 screens. See attachment, I cannot see why the alternator isn't charging the battery. Any ideas? You can see the voltage warning light and the discharge on the ammeter. The red alt switch is on and when switching it on/off nothing happens.

Sorted it, starter motor was engaged.
