120A Bosch alternator modified to 15.3v. A simple diode mod to give 15.3v instead of the factory 14.5v when charging a single lead acid battery (test only).
PLEASE NOTE: This is merely a proof of concept. The diode used in this video is only 3A rated and not enough on it's own for the field current at max load. After the video once fitted back to the engine, I swapped the diodes out to 2 parallel diodes in series (4x 3A diodes in total). This bumped the voltage up to about 15.8v at the alternator.
Expected field current is aprox. 6-8A max, so a single 3A diode could get very hot and blow quite quickly under heavy load.
I must also mention any modification you do to your alternator or vehicle is done so at your own risk and I am not responsible for the result. Thank you :)
