Solution

1. Preparation

Tools Required:
- Multimeter
- Socket set
- Wrenches
- Jumper wire
- Safety glasses
Safety Warnings:
- Disconnect the battery before working on electrical components to avoid short circuits.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion from the battery terminals using a wire brush.
- Tighten the terminal connections to ensure a solid contact.
Test Battery Voltage
- Use a multimeter to check the voltage.
- If voltage is below 12.6 volts, recharge or replace the battery.
Replace Battery (if necessary)
- Remove the negative (-) cable first, followed by the positive (+) cable.
- Remove the battery hold-down bracket and lift out the old battery.
- Place the new battery in the tray and secure it with the hold-down bracket.
- Connect the positive (+) cable first, followed by the negative (-) cable.

3. Starter Motor Inspection and Replacement

Check Starter Connections
- Inspect the starter motor connections for looseness or corrosion.
- Clean and secure any loose connections.
Test Starter Motor
- Use a jumper wire to bypass the solenoid: connect the positive terminal of the battery directly to the starter motor terminal.
- If the starter engages and the engine cranks, the issue may lie with the solenoid.
Replace Starter (if necessary)
- Disconnect battery cables.
- Remove the starter motor bolts and disconnect the wiring.
- Install the new starter motor and reconnect the wiring.
- Reattach the bolts and ensure they are torqued to the manufacturer’s specifications.
