If terminal B is disconnected whilst the alternator is functioning, the voltage of the battery gradually drops until it
starts discharging. As long as the voltage at terminal S is more than 13V the M-IC maintains the voltage at ter-
minal B at 20V, protecting the alternator and the rectifier in the moment in which the voltage at terminal S drops
under 13V. The M-IC reveals it through Tr3 and activates the warning light.
