Chrysler 300/300 Touring/300C, Dodge Magnum. Manual — part 423
3. The relay normally open terminal (87) is connected to the common feed terminal (30) in the energized position.
This terminal supplies battery voltage to the starter solenoid field coils. There should be continuity between the
cavity for relay terminal 87 and the starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair the
open circuit to the starter solenoid as required.
4. The coil battery terminal (85) is connected to the electromagnet in the relay. It is energized when the ignition
switch is held in the Start position and the clutch pedal is depressed (manual trans). Check for battery voltage at
the cavity for relay terminal 86 with the ignition switch in the Start position and the clutch pedal is depressed
(manual trans), and no voltage when the ignition switch is released to the On position. If OK, go to Step 5. If not
OK, check for an open or short circuit to the ignition switch and repair, if required. If the circuit to the ignition
switch is OK, see the Ignition Switch Test procedure in this group.
5. The coil ground terminal (86) is connected to the electromagnet in the relay. It is grounded by the PCM if the
conditions are right to start the car. For automatic trans. cars the PCM must see Park Neutral switch low and
near zero engine speed (rpm). For manual trans. cars the PCM only needs to see near zero engine speed (rpm)
and low clutch interlock input and see near zero engine speed (rpm). To diagnose the Park Neutral switch of the
trans range sensor refer to the transaxle section. Check for continuity to ground while the ignition switch is in the
start position and if equipped the clutch pedal depressed. If not OK and the vehicle has an automatic trans. verify
Park Neutral switch operation. If that checks OK check for continuity between PCM and the terminal 86. Repair
open circuit as required. Also check the clutch interlock switch operation if equipped with a manual transmission.
If OK, the PCM may be defective.
SAFETY SWITCHES
For diagnostics of the Transmission Range Sensor, refer to the Transaxle section for more information.
If equipped with Clutch Interlock/Upstop Switch, refer to Diagnosis and Testing in the Clutch section.
IGNITION SWITCH
After testing starter solenoid and relay, test ignition switch and wiring. Refer to the Ignition Section or Wiring Dia-
grams for more information. Check all wiring for opens or shorts, and all connectors for being loose or corroded.
BATTERY
For battery diagnosis and testing, refer to the Battery section for procedures.
ALL RELATED WIRING AND CONNECTORS
