Troubleshooting Tips When Your Car Won’t Start After Connecting the Battery

The car attempts to start when the battery is connected.

Car Tries To Start When I Connect The Battery

When connecting a car’s battery, there are a few possible scenarios which can happen. In some cases, the car may start up automatically due to its internal starter motor, in other cases it may take several turns of the key to power the vehicle. Sometimes however it can be possible for the car to try and start when you connect the battery, even without turning the key. This is due to an electrical fault where power is inadvertently fed to the starter motor. If you experience this problem it is important that you have your vehicle checked out by a qualified mechanic in order to identify any faulty wiring or circuit issuesthat could potentially lead to serious problems if not attended to promptly.

Checking the battery

When you connect the battery to the car to try and start it, it is important to take a few moments to check that the battery is in good working order. This can be done by verifying the battery’s charge with a load tester or multi-meter. If the test results are not satisfactory, it may be necessary to change or replace the battery. When choosing a replacement type, make sure that it has been approved for use in your car and that it is of the same size and voltage as your existing battery. In addition, make sure to test its operation before installation.

Check for Power Leaks

It is also important to check for power leaks when attempting to start a car with a new or recently replaced battery. This can be done by verifying fire paths using a chiltronics device, as well as inspecting insulation and wiring integrity for any signs of damage or fraying. If any of these issues are detected, they should be addressed prior to attempting to start the car.

Check Ignition System

The next step when trying to start a car with a new or recently replaced battery is to check the ignition system. This includes verifying that spark plug connectors are tight and testing starting capability of starter motor. In addition, inspect wiring and distributor caps for signs of wear or damage that could impact starting capability.

Test Charging System

Finally, when trying to start a car with a new or recently replaced battery, it is important to test the charging system as well. This can be done by checking voltage at Battery terminals while engine is cranking and inspecting alternator belt tension and condition. If either of these components are not in optimal condition, they should be replaced prior to attempting to start the engine again.

Inspect Distributor Cap and Rotor

When trying to start a car and the battery is connected, it is important to inspect the distributor cap and rotor. This helps to determine if there is any damage or wear that could be preventing the car from starting. Reviewing the wear pattern on the cap terminals and rotor surface can help to identify any issues that may be causing the car not to start. Additionally, take a look at the condition of spark plugs and wires as these can also be contributing to why the car wont start.

Cleaning Carbon Deposits in Engine

If there is a lot of carbon build up in the engine, this could also be causing problems with starting your vehicle. One way to clean carbon deposits from an engine is by removing valves for cleaning deposits on chamber walls. This should help remove any extra build up that could be preventing your car from starting when you connect your battery.

Testing Regulated Voltage System

The regulated voltage system (RVS) needs to be tested in order to determine why your car won’t start when you connect the battery. This can be done by analyzing data from a diagnostic scan tool, which will tell you if all sensors are providing proper readings. Additionally, examine all fuses in your interior fuse panel for possible blown ones as well as inspecting cable connections for corrosion issues which could potentially prevent your vehicle from starting.

Running Diagnostic Tests

To further investigate why your vehicle wont start when you connect the battery, running diagnostic tests can provide helpful information about what might be causing this issue. To do this, connect a trouble code reader to the engine computer and utilize data provided by this tool in order to identify what’s triggering cause may be behind why your vehicle won’t start when you try connecting it with a battery.
