Consult a wiring diagram to identify the wires. The voltage regulator should regulate voltage between 13.5 and 14.5 volts (6volt systems should be approximately half of 12volt readings) once the engine has been running for a few minutes. If voltage is too high or low, but the generator full fields, the voltage regulator is probably bad. Before purchasing a new regulator, make sure The only way to adapt these to your 12V solar system is to create these tensions with two voltage regulators and connect them correctly at the right points in the battery compartment. It would be very smart to make a separate 12V connection with a diode.and a voltage regulator inside the body of the product. But to do this you must open the case up and you will invalidate all guarantees on the equipment by doing this: Put the connection from the solar system onto the big electrolytic A ninevolt regulator can also be used here, but they're less commonly available than the 12volt type. The second regulator, IC2 (LM78L62), has to be a lowervoltage type, shown here as a 6.2volt type, as its feed voltage is going to be the regulated output voltage from the previous stage. We are essentially going to have two stages of regulation here. This second, twiceregulated supply feeds the oscillator circuit exclusively. With this arrangement, any fluctuations in the rest of the A voltage.regulator controls alternator output according to system demands by regulating the flow of current through the alternator field winding. Two approache; to regulating alternator field current are in common use. The Positive or Ptype al. ternator and regulator sys. tem, the more common type of externally mounted voltage regulator, is installed between the 12volt positive source (battery positive) and the field terminal of the alterna. tor to regulate the applied voltage to control battery condition and alternator and voltage regulator performance. Automotive 12volt batteries are comprised of six cells with 2.1 volts each. Fullycharged batteries in good condiThe alternator brushes require replacement if the overall length is less.than their width. You can use a piece of .060 wire to hold back the sprung brushes. It's much easier to remove this assembly from the alternator to load the brushes. tion should have 12.6 volts during testing. As 12volt batteries degrade, +. 12. Volt. Supply. The —30 volt supply is the reference voltage for the comparator amplifier Q536 and Q546. The output of the comparator amplifier is applied to the base of emitterfollower Q543 which controls the current through the series current regulator transistor Q547.There is a rule of thumb that says if a battery is using too much water, the voltage regulator is set too high; if the battery doesn't seem to stay charged, then the voltage regulator is set too low. Essentially that.is true. However, once again Murphy sneaks into the picture. In flight the battery is recharged by the alternator; this happens because the mechanic has set the voltage regulator to a value slightly above battery voltage. A 12 volt battery system will have an alternator output of 14.25 Because in series connections, volt goes up and amp stays the same. (And in parallel connections, amp goes up and volt remains the same = thicker wire or cables) Another very important example: If you have 12volt solar panels (open circuit) and want to put it through a 12/24volt solar regulator, then you can only put 2 in series. Otherwise, you will exceed the 24volt limit or voltage, and also remember the connections on the battery side ('output').must be 12/24 volt (voltage written Switch Regulator B+ Alternator FIGURE 1521 Btype regulator connection. Regulator Switch B+ Alternator FIGURE 1522 An isolated field alternator allows connection of either an A or Btype regulator. three diodes will perform singlephase rectification of each phase of the alternators' windings. Singlephase rectification means only a maximum of half the alternators' voltage output can excite the rotor. Some voltage regulators use an analog voltage signal to modulate or change the Because the alternator is connected to all these circuits, the voltage regulator will supply the highest possible current ow to the rotor for maximum magnetic eld strength. As the Charging at voltages.above 15 volts (12volt system) and 31 volts (24volt system) causes: Batteries to gas excessively Batteries to overheat and lose electrolyte through electrolysis Battery plates to shed grid material, buckle, and generally become heat damaged as the temperature rises above 125°F (52°C)
