2.4.1 Charge Generator current<br />
The unit uses the Charge generator current input to detect when the engine is running. The<br />
<strong>GEN</strong>-<strong>AUTO</strong> connection effectively replaces the usual charge indicator lamp. It supplies current to<br />
the rotor coil from the battery until the engine is running, at which time the Charge Generator<br />
powers the rotor via the diode trio. The <strong>GEN</strong>-<strong>AUTO</strong> circuits sense the resultant voltage at pin 18.<br />
This is initially low at near Battery -, as the circuit supplies a high current to the rotor coil, rising<br />
to near Battery + once the engine is running. Figure 2.9 shows the arrangement.<br />
