^
Locate the solid blue wire (temperature sensor) and using a scotch lock connector, attach the resistor wire to the blue wire.
IMPORTANT
^
Repair the harness with electrical tape including the scotch lock to prevent:
*corrosion of the scotch lock connector
*moisture entering the control unit harness
The control unit senses the engine temperature by sending current through the temperature sensor. The resistance of the sensor is higher at colder engine
temperatures. Therefore, the colder the engine the less current can flow through the sensor.
By connecting the "resistance wire" from the starter motor, additional current is supplied to the temperature sensor only while cranking. This additional
current from the starter reduces the current flow from the control unit, indicating the engine is colder than it actually is. This permits a richer mixture
while cranking and improves starting ability.
NOTE!
Control unit P/N 1317029-5 for B23F M.Y. 1983 is superceded by control unit P/N 1346563-8 (original equipment for B23F 1984). Therefore, to avoid
the possibility of startability complaints, when replacing control units on B23F 1983; the resistor wire P/N 1189980-4, should also be fitted.
