Don't throw away your used regulator just yet because it can be assembled into useful items and has a high selling value (hundreds of thousands).
One of the items that we can make from used regulator is a motorcycle battery charger (a tool for charging motorcycle batteries from used regulator)
We can take advantage of used motorbike regulator which still has a normal charging system, regulator is usually divided into two paths, namely the path to the lamp and the battery charging path.
The path to the lighting lamp functions to regulate/stabilize the current to the lamp so that the lamp does not break easily, while the path to charging the battery functions as a battery charger (battery) so that the battery continues to be charged.
If one of the paths is damaged, usually the regulator is replaced with a new one to suit its function and we can use the remnants as a manual battery charger (charger).
And this video is how to assemble/make a motorcycle battery charger from used regulator.
