The installation steps for the Daihatsu 12V generator are similar to those for general automotive generators. Here are the specific installation steps: •  Preparation Work: Prepare tools such as a socket wrench, open-end wrench, ratchet wrench, and a 12V generator compatible with the Daihatsu model. Park the vehicle on a flat, stable surface and disconnect the negative terminal of the battery to prevent short circuits during installation.  •  Removing the Old Generator: Locate the generator belt tensioner, use a wrench to loosen the tensioner to slacken the belt, then remove the belt. Next, disconnect the wires connected to the generator, remembering the positions and methods of the wire connections for correct reinstallation later. Finally, use a socket wrench or open-end wrench to loosen the generator's fixing bolts and nuts, and carefully remove the old generator.Clean the installation location: Use cleaning tools to remove dust, oil stains, and debris from the installation location, ensuring the mounting surface is clean and tidy. This will ensure that the new generator is installed more securely and reduce the risk of faults caused by poor contact.  •  Install the new generator: Place the new generator stably on the installation location and initially secure it with bolts and nuts, but do not tighten them to leave room for subsequent adjustments.  •  Connect the wires: Connect the wires to the corresponding terminals of the new generator according to the previously recorded positions and methods. Usually, alternator terminals are marked with "+", "F", "-", "N", etc. The "+" terminal is connected to the positive pole of the battery, the "F" terminal is connected to the F terminal of the regulator, the "-" terminal is grounded to the vehicle body or the negative pole of the battery, and the "N" terminal is connected to the charging indicator control circuit. Ensure that every connection is secure and not loose.Install the belt: Put the belt accurately on the generator's pulley, and adjust the belt tensioner to give the belt appropriate tension. If the belt is too loose, it will slip and affect power generation efficiency; if it is too tight, it will accelerate the wear of the belt and the generator bearings.  •  Inspection and fastening: Check and fine-tune the position of the generator and the belt tension. After ensuring everything is correct, fully tighten the fixing bolts and nuts.  •  Restore battery connection: Reconnect the negative pole of the battery, start the car, and check if the generator is working properly. You can use a multimeter to measure the voltage on the battery terminals. When the engine is running at idle speed, the voltage should be between 13.5V and 14.5V. After turning on electrical equipment such as headlights and air conditioners, the voltage should remain above 13V.

The core precautions for installing the Daihatsu 12V generator are safety against short circuits, accurate wiring, and meeting the standards for torque and belt tension, as follows: 1. Core of Safe Operation •  It is necessary to disconnect the negative pole of the battery first, and avoid tools touching the positive and negative poles of the generator or the terminals at the same time throughout the process to prevent short circuits from burning out the generator and the vehicle's ECU.  •  The vehicle must be parked on a flat surface and the handbrake pulled tightly. If operation under the vehicle is required, it must be fixed with a jack and a safety bracket. It is forbidden to work with only the jack for support.  •  Wear gloves and goggles to avoid scratches from belt rebound and bolt slippage, and keep away from high-temperature engine components (such as the exhaust pipe).II. Key Installation Details •  Wiring must strictly correspond to the markings: The generator terminal "+" is connected to the positive line of the battery, "F" to the regulator, "-" or the unmarked terminal is grounded (connected to the vehicle body), and "N" to the charging indicator light. Incorrect connection will directly burn out components.  •  Fixing bolts should be tightened to the specified torque (most Daihatsu models use 25-30N・m, subject to the specific vehicle manual). Loose bolts will cause vibration and abnormal noise, while over-tightening may damage the mounting bracket or generator housing.  •  Belt tension should be controlled such that "pressing the midpoint causes a sag of 1-2 centimeters". Too loose a belt will slip, resulting in insufficient power generation; too tight a belt will accelerate bearing wear. During installation, align with the pulley groove to avoid deviation.  •  For a new generator, check that its model, power, and mounting holes match those of the original vehicle to avoid compatibility issues. Clean the oxide layer on the terminals before installation to ensure good contact.III. Testing and Subsequent Inspections •  After starting, measure the voltage with a multimeter: 13.5-14.5V at idle. After turning on electrical loads (headlights, air conditioning), it should not be lower than 13V; otherwise, there may be poor wiring or a loose belt.  •  During operation, check that there is no charging fault light (battery icon), the generator has no abnormal noise, peculiar smell, and the housing does not overheat.  •  Recheck 1-3 days after installation, focusing on whether the wiring terminals are loose and whether the belt is misaligned to avoid hidden dangers during long-term use.IV. Vehicle Model-Specific Notes •  For some older Daihatsu models (such as Charade, Mira), the generator requires the removal of the front bumper or air intake hose. When disassembling, properly mark the parts to avoid incorrect installation that may affect the seal.  •  For generators with an integrated regulator, ensure that the regulator plug is fully inserted during installation to prevent loosening or water ingress.
