MEMO CHARGING SYSTEM When the starter switch (5) is turned to the "ON" position, an initial excited current flows to the field coil of the alternator (7) through the battery relay (2) and circuit breaker (4). When the engine is started from this condition the alternator (7) starts charging. The current flows from the "B(B+)" terminal of alternator (7) circuit breaker (4) battery relay (2) battery (1). The alternator also supplies electric current to other electrical components. When the alternator (7) starts to operate, a current flows from the "R(I)" terminal of alternator diode (8) battery relay (2) coil securing a path for the charging current to the battery (1).
Thus preventing the possibility of a high voltage build up and possible damage to the electric system.
