Sorry for not giving a reaction was very busy the past days.
Unfortunately we still don't have a working altenator. Got a refurbished one from a friend of ours and tried to contact it as i had shown but we don't get anything. The output of the battery is still around 11 volts ,So it's discharging. (Yes we have converted to 12 volts)
Made a little drawing where the ignition goes to. Hope somebody can help because I really wanna give up
