The regulator performs rectification and voltage regulation. The regulator converts A.C.
into D.C. which flows through the power consuming circuits to the battery, maintaining
battery change.
If the battery voltage exceeds a certain level, the D.C. is cut off from the charging
circuit to prevent over charging. An isolating switch or fuse could be used.
For best results it is recommended that positive and negative of the regulator go
directly to the battery.
