Start the working vehicle and let it run for a few minutes to charge the dead battery. Then, attempt to start the 2015 Ford Edge. Once it starts, remove the cables in the reverse order of connection, starting with the negative clamp from the chassis, then the negative clamp from the good battery, followed by the positive clamps.
After jump-starting, drive the vehicle for at least 20-30 minutes to allow the alternator to recharge the battery.
- Jumper Cable Connection Order:
- Positive (+) clamp from good battery to positive (+) terminal of dead battery.
- Negative (-) clamp from good battery to a clean metal ground on the dead vehicle’s engine block or chassis.
- Start the vehicle with the good battery.
- Allow it to run for a few minutes.
- Attempt to start the vehicle with the dead battery.
- Jumper Cable Disconnection Order (Reverse):
- Negative (-) clamp from the chassis/engine block.
- Negative (-) clamp from the good battery.
- Positive (+) clamp from the dead battery.
- Positive (+) clamp from the good battery.
26. The Role of Engine Ground Straps
Engine ground straps (also known as ground cables or bonding straps) are essential for completing the electrical circuit in your 2015 Ford Edge. They connect the engine block and chassis to the negative terminal of the battery, providing a low-resistance path for electrical current. A faulty or corroded ground strap can lead to a myriad of electrical issues, including starting problems and erratic system behavior, often mistaken for battery problems.
If the ground strap is damaged, loose, or corroded, the battery might appear to be the culprit, but the real issue is the inability of electricity to properly return to the battery. This can cause voltage drops and poor performance of electrical components. Inspecting and ensuring the integrity of the engine ground strap is an important part of electrical system maintenance.
| Component | Function | Symptoms of Failure |
|---|---|---|
| Engine Ground Strap | Provides a return path for electrical current from the engine and chassis to the negative battery terminal. | Slow cranking, flickering lights, intermittent electrical issues, starting problems, radio static, dashboard warning lights. |
A corroded or loose ground strap can mimic many battery and charging system issues.
27. Understanding Battery Voltage Readings
Understanding basic battery voltage readings can help you gauge the health of your 2015 Ford Edge battery. A fully charged battery at rest (engine off, no accessories running for at least a few hours) should read approximately 12.6 volts. A reading of 12.4 volts indicates about a 75% charge, while 12.2 volts is around 50% charged.
A battery reading below 12.0 volts is considered discharged and may not have enough power to start the engine.
When the engine is running, the voltage should increase to between 13.7 and 14.7 volts. This indicates that the alternator is functioning and charging the battery. If the voltage remains below 13.0 volts while running, the alternator may be weak or faulty.
If it exceeds 15.0 volts, the voltage regulator might be malfunctioning, leading to overcharging.
