my Ram 1500 DT (2019-Present) won't start and just clicks, what to do

Solution

1. Preparation

• Gather tools and parts.
• Disconnect the negative battery terminal to prevent accidental shorts.
• Ensure the vehicle is in park or neutral.

2. Battery Inspection and Replacement

1. Inspect Battery Terminals:

   • Clean any corrosion using a mixture of baking soda and water.
   • Tighten the terminal connections securely.

2. Test Battery Condition:

   • If the voltage is below 12.4 volts, proceed to replace the battery.
   • Remove the old battery by loosening the terminal bolts and carefully lifting it out.

3. Install New Battery:

   • Place the new battery in the tray.
   • Secure the battery hold-down bracket.
   • Connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Testing and Replacement

1. Test Starter Motor:

   • Locate the starter motor (usually at the rear of the engine near the transmission).
   • Use a multimeter to check voltage at the starter terminal when the ignition is turned to the start position.

2. Replace Starter Motor (if necessary):

   • Disconnect wiring from the starter motor.
   • Remove the mounting bolts (typically 2-3) securing the starter to the engine.
   • Install the new starter motor by reversing the removal steps.
   • Torque the mounting bolts to manufacturer specifications (usually around 10-15 ft-lbs).

4. Relay and Ignition Switch Check

1. Inspect Starter Relay:

   • Locate the starter relay in the fuse box.
   • Swap it with a similar relay to see if the issue resolves.

2. Check Ignition Switch:

   • If the click persists, test the ignition switch by removing it and testing continuity in different positions.
   • Replace the ignition switch if defective.
