Warning lamp, charging
The charge warning lamp is situated in the top right-hand corner and informs the driver whether or not the generator is charging.
The lamp is powered by the main instrument unit and is grounded internally by the main instrument unit.
If the generator is not rotating or if it is not charging for some reason, pin 6 on the main instrument unit will be grounded via the regulator through the generator field winding, whereby the lamp will come on.
Meanwhile, the central warning lamp will come on and at engine speeds above 310 RPM, MIU will send a request to SID to activate the acoustic signal.
When the generator is charging, its D+ and B+ terminals will have the same voltage. The MIU input will then be supplied with B+ voltage, whereby the control unit will turn off the lamp.
