Solution

1. Preparation

Gather tools: Multimeter, socket set, torque wrench, battery terminal cleaner, and a jumper cable.
Ensure the vehicle is in park or neutral with the parking brake engaged.

2. Battery Inspection and Replacement

Sub-step 1: Disconnect the negative battery terminal using a socket wrench.
Sub-step 2: Clean the battery terminals and cable connectors with a battery terminal cleaner.
Sub-step 3: Reconnect the battery terminals securely.
Sub-step 4: If the battery voltage is low, replace the battery with a new one, ensuring it meets the specifications for the Ram 1500.

3. Starter and Relay Check

Sub-step 1: Locate the starter relay in the fuse box.
Sub-step 2: Swap the starter relay with another relay from the same fuse box to test functionality.
Sub-step 3: If the clicking persists, access the starter motor, usually located on the lower side of the engine near the transmission.
Sub-step 4: Disconnect the wiring harness from the starter and inspect it for damage or corrosion.
Sub-step 5: Use a multimeter to test the starter motor by applying direct power to see if it engages. If it does not, replace the starter motor.
