The installation steps for the Jiefang Aowei 24V starter are as follows: •  Preparation: Prepare tools such as wrenches and screwdrivers. Ensure that the vehicle's engine is turned off and the power supply is disconnected to ensure operational safety.  •  Disconnect the power supply: Remove the negative battery cable to prevent dangers such as short circuits during the installation process.  •  Locate the starter: The starter is usually located at the junction of the engine and the transmission.  •  Install the new starter: Accurately align the new starter with the installation position and place it in, then fix it with bolts. When tightening the bolts, operate according to the specified torque to avoid over-tightening or under-tightening.Connecting electrical circuits: Connect the electrical plug and wires of the starter, ensuring the connections are secure without looseness or short circuits. For a 24V starter, pay attention to the series connection of the two batteries: connect the positive pole of the starter to the positive pole of the battery, and the negative pole to the vehicle's grounding point, which is generally the frame or the engine.  •  Restoring power: Reconnect the negative cable of the battery.  •  Inspection and testing: After installation, check if the starter is securely installed and if the electrical connections are normal. Then start the vehicle and observe whether the starter operates normally.

Precautions for installing the Jiefang Aowei 24V starter mainly focus on "electrical safety, installation accuracy, and compatibility" to avoid short circuits, component damage, or starting failures: I. Precautions before installation •  Ensure that the starter model is completely compatible with the Jiefang Aowei vehicle model, with a voltage of 24V, and that the power and mounting holes are consistent with the original factory specifications to prevent installation failure or circuit burnout.  •  Check that the new starter has no external damage, no rust on the terminals, and no burrs on the gear meshing surface to ensure the component is in good condition.  •  Clean the oil stains, rust, and debris from the starter mounting surface to ensure a tight fit and avoid uneven bolt stress.  •  Prepare tools such as insulating gloves, a torque wrench, and wire terminal cleaner. Disconnect the vehicle's main power supply during operation and never work with live electricity.II. Precautions During Installation •  Electrical connections must have "clear positive and negative polarities": The positive terminal of the starter is connected to the positive circuit of the battery, and the negative terminal (ground wire) is connected to a reliable grounding point on the frame or engine. Reverse connection is strictly prohibited, as it will burn out the starter coil or fuse.  •  Terminal connections must be secure: Insert the plug completely into the slot. After tightening bolt-type terminals, gently pull them by hand to ensure there is no looseness. This avoids heating or sparking during startup due to poor contact.  •  Tighten the fixing bolts "diagonally and sequentially": Use a torque wrench to tighten according to the vehicle's specified torque (typically 40-55Nm). Avoid loose bolts, which can cause the starter to vibrate during operation, or over-tightening, which can damage the mounting base.  •  Check the gear meshing clearance: After installation, manually rotate the starter gear to ensure smooth meshing with the engine flywheel ring gear, with no jamming or abnormal noise. If there is an issue, adjust the installation position.  •  Avoid wire extrusion: Organize the electrical wires, keeping them away from high-temperature areas of the engine and rotating components to prevent wire abrasion and short circuits.III. Post-installation Precautions •  Before restoring power, recheck the wiring to ensure it is correct, with no reverse connections or wrong connections, and make sure the main power switch is in the off state.  •  First start-up test: Start the engine briefly, observe whether the starter runs smoothly without abnormal noise, and can return quickly after starting to avoid long-term meshing wear of the gears.  •  Check circuit safety: After starting, touch the terminals; there should be no overheating, the battery voltage should be stable (the normal voltage of a 24V system is approximately 25-28V), and there should be no under-voltage or short-circuit alarms.  •  If it cannot start after installation, first check the wiring, fuses, and battery power. Do not repeatedly force start it to avoid aggravating component damage.IV. Taboo Items •  It is forbidden to operate in a humid environment or when hands are wet to prevent electric shock or short circuit.  •  It is not allowed to directly touch the starter terminals with metal tools to avoid accidental grounding and sparking.  •  Do not mix 12V and 24V components. A 24V starter connected to a 12V power supply will fail to start, and connecting to an excessively high voltage will burn out the coil.

Instead, it is a synthesis of various automotive maintenance knowledge and experience. Some of its contents are consistent with the precautions for starter installation on professional automotive websites such as Autohome and PCauto. For example, articles on Autohome like "Disassembly and Assembly of Starters" and "How to Disassemble and Assemble a Starter" mention points such as disconnecting the power supply before installation, paying attention to the order of electrical connections during installation, and strictly prohibiting rough handling like hitting or knocking. PCauto's articles such as "Starter Disassembly and Assembly Process" and "How to Correctly Install a Starter" also elaborate on similar installation precautions, such as confirming that the starter model matches the vehicle and tightening bolts to the specified torque. Additionally, it may have referenced relevant automotive repair manuals and the practical operational experience of maintenance personnel.
