how to wire an alternator to charge a battery

... 64-72 charging system wire up using GM 3 wire internally regulated alternator - Duration: 13:25. They have to perform some "magic" with internal voltage-drop or rpm detection; and some days, magic just doesn't work, which is why no manufacturer would ever use a 1-wire alternator. If the voltage is significantly lower than that, then there could be an issue with the alternator, but there could also be an issue with your belt(s) or pulley(s) or wiring. Most cars originally came with a 3-wire alternator. The setup includes a temperature sensor on the alternator which limits its output by keeping the alternator within the allowed temperature. The headlights dashboard lights radio and interior lights all rely on the alternator to keep the battery … FESER Alternator battery charge power turn on/off RPM speed test. This is the most common leisure battery charging method used and is fitted to nearly every van. We snake the new wire into place and feed it into the engine bay. Next month we are going to look at some ideal charging scenarios using battery combiners and isolators to automate and simplify the charging process. This is the main current feed that charges the battery and powers the car when the engine is running. On our 1964 Chevelle, the alternator charge wire is attached to clips that tuck beneath the upper radiator support channel. I am sure trailer battery will charge as long as wiring to trailer is sufficient to carry the load. If your unit requires a separate ground run a short wire from the alternator to a convenient point on the engine block or the chassis. As its name implies, the 3-wire alternator has three electrical connections to it. The alternator is externally regulated by a Balmar MC-614-H regulator. Then, test voltage at the rear of the alternator and compare that to the voltage at the battery. The ratio between the battery bank and the alternator will dictate how long it will take for the charging voltage to reach 14.4 volts. *This diagram shows the simple wiring diagram for negative ground Delco SI series alternators. In the next drawing, below, the alternator is only charging the Lithium battery. Alternator demo wiring connection to battery. One-wire alternators are internally MORE complex than 2/3 wire alternators and therefore less reliable. This enables the vehicle battery, once fully charged to split the charge it receives from the alternator with the leisure battery. Any time you upgrade your alternator, you should also strongly consider upgrading the gauge (size) of the wire that charges the battery as well as the fusible link in case of a short. The chart below charts the gauge wire required based on alternator amperage output and length of wire. Automotive charging systems use a charge wire that runs from the alternator to the battery. With key on power is then transferred through the no charge indicator light to the #1 spade on the alternator regulator connection. If the voltage at the battery is within 0.5-volt of the alternator voltage, then the charge wire is okay. A split charge relay is effectively a switch, that when closed connects the vehicle and leisure battery together. Alternator will produce what ever amp is required to maintain 14.2 amps. That is the output of the alternator at the battery and that range is needed to keep the battery properly-maintained. Alternator will raise voltage to 14.2 V to run what ever electrical load vehicle and trailer are using. In stock applications, this wire usually is between 10 and 12-gauge. 8/15 If you’re upgrading the output size of your alternator, it is also highly recommended that you also upgrade the charge wire … * The ignition switch is most commonly powered from the starter battery stud, but source may vary depending on application.
