Running of the Generator

Running and testing of the petrol generator with 12V alternator.
25V output unloaded

Hello everybody
We are currently doing a generation project.
We have been given the fossil fuels theme. For this we have a 5hp Honda engine.
Currently we are trying to find a 24v alternator for engine to generate with.
We will then be connecting it to a battery bank that our whole class is contributing
 towards.
Thx #Hohmies
