Power is also applied to the ballast resistor bank thru 88b. The ballast resistors speed up the response time of the injector solenoids. When the ignition switch is advanced to the start position, power is applied to the starter solenoid and also to CR1 relay thru terminal 86a, 86. A diode in series with CR1 coil prevents power from flowing back out. The cold start valve also energizes as the starter cranks.
Cold start is under the control of the thermo- time switch.
The cold start valve will only inject fuel if the temperature is low enough to require it and the injection will cease after a preset time due to heating of the thermo-time switch during cranking. If you crank for a long time and the engine still doesn't start, cold start injection will be turned off to prevent flooding. CR1 contact powers the electric fuel pump and the Aux Air Regulator. Because of the holding circuit, power can now be removed from terminal 86 as the starter is de-energized. The holding circuit has a resistor built into the relay enclosure which provides sufficient current to keep CR1 energized.
