How do you convert a 6 volt electrical system to 12 volt?
Change the 6 volt generator to a 12 volt alternator. Replace the starter & battery with a 12 volt. Replace every single bulb on the vehicle with a 12 volt bulb. You may also need to replace the coil. Also replace any electronic devices designed for 6 volts with ones designed for 12 volts.

With a Step Down transformer. But you will probably have a hard time finding a 240 volt unit. 120 volts units are readily available. It depends on how big of a transformer th…at you are looking for. There are many control transformers in the 50 to 500 VA range that have dual primary and dual secondary. The primary side can be connected to 240 volt or 120 volt and the secondary can be connected for either 12 or 24 volts.
If you really wanted to do that you'd have to pull the winding off the coil and replace it with another winding. It'd be far easier simply to replace the 12V unit with a 24V u…nit.
Stepping down AC voltage To step down 12 VAC to 3 VAC, you could use a step-down transformer with a winding ratio of 4:1 between primary and secondary. Stepping Down DC Vo…ltage There are a number of ways one can step down 12 VDC to 3 VDC, but they basically fall into three categories: Unregulated voltage dividers Linear voltage regulators Switching voltage regulators Voltage Dividers A voltage divider is two or more resistors connected in series with a power source, which causes the voltage to be divided between them. For example, if you were to connect a 30 ohm and a 10 ohm resistor in series across a 12 volt supply, the voltage across the two resistors would be 9 volts and 3 volts, respectively: __________________VT = 12 V _____________________ |...................R1......................................... R2........................| +12V----| 30 ohm |--------+3V----------| 10 ohm |-------Ground |...................................... |................................................... | --------------VR1 = 9V-------------------------VR2 = 3V-------------- RT = R1 + R2 VR1 = VT R1 / RT VR2 = VT R2 / RT Note that trying to draw power from the point between those resistors would quickly cause the voltage to drop because of the parallel resistance of the load. Instead, substitute the device as one of the resistors. So, to get 3V to your device, you could measure the resistance of the device, then pick a resistor that is 3 times the resistance of the device, and connect the device to 12V in series with that resistor. The resistor will have to have a wattage rating of at least 3 times the power used by the device (or 9 watts divided by the resistance of the device), to keep from overheating. Also, If you are using batteries for power, make sure that the resistors you connect are of a high value in the order of kiloohms or else the resistor divider network could drain your power source. The problem with this approach is that if the input voltage (12V) changes, or the resistance of the device fluctuates, the voltage to the device will fluctuate. Basically I would only use this method for simple resistive loads such as light bulbs. Linear Voltage Regulator A linear voltage regulator is a circuit that acts like a voltage divider, but automatically changes resistance to maintain a constant output voltage regardless of change in the current drawn from its output, or variations in the input voltage. While the circuit itself has a bit of complexity, integrated circuits that perform this function are commonplace and inexpensive. One the cheapest and most readily available is the LM317T ($2.29 at Radio Shack) regulators, which accepts an input of up to 40V and has an output voltage of 1.2V to 37V, determined by a pair of resistors attached to the regulator. This regulator can provide up to 1.5 amps of output, more with the addition of external transistors. I've posted a URL to the datasheet for this regulator in the Links section. Linear shunt regulator A shunt regulator made from a resistor and a zener diode is another type of linear regulator. Connect a resistor from 12V to the cathode of a 3V zener diode, and the anode to ground, then connect the load from the cathode to ground. The zener diode will draw current as needed to hold the load voltage near 3V. The output voltage will vary with load current, although not as much as a voltage divider. It will also vary with temperature. The zener diode and resistor must be sized correctly to handle the currents involved. Switching Voltage Regulator One of the disadvantages of linear regulators is that they are very inefficient, especially when drop between input and output voltages is large, because the extra voltage has to be dissipated away as heat. In the case of regulating 12V down to 3V, you are basically throwing away 3/4 of the power being used, meaning an efficiency of less than 25%. In some applications this might be acceptable, for example in an automotive application where plenty of current at 12V is readily available. In other applications such as battery powered devices, such a waste would be a bad thing. Switching voltage regulators work on a much different principle, switching the power on and off at a high rate of speed to regulate the output voltage (see the URL for DC-to-DC Converters in links for a more detailed explanation). They offer efficiencies of up to 95%, and can even output higher current or voltage than the input. They are more expensive than linear regulators, but offer more performance per buck - for example, for $9.25US through Digi-Key the LT1074 (see link) can provide up to 10 amps of output, and accept input voltages up to 60V. Actualy two types passive and active. No matter what names to add to that.
Yes. Since the coil is run at full voltage when starting 12 volts may be too much for a 6 volt ignition coil. It would be at about 8 volts when running. There is a starting re…sistor.
Buy an inverter with the voltage and power specification per your application. There are lots of sources on the Web.
I believe this is a 12 volt system. an easy way to check this is a multi-meter. I would recommend purchasing this tool because it always comes in handy and is worth the money …when working with electrical systems.
If you want to convert 24v AC into 12v Ac, it's simple. Just get a transformer to convert 24 volts into 12 volts. This is called a stepdown transformer. If you want to… convert 24v DC into 12v DC, it's more complicated. First you have to change the 24v DC into 24v AC by a switching converter that changes DC into AC. Then you would use a stepdown transformer as in the former example. Once the 24v AC is converted to 12v AC, then you use a rectifier bridge to change the 12v AC into 12v DC.
No, you cannot.
You should use ULN2003 or LM398 driver for it
You would need a transformer specially made to do this. Of course, this transformer would need a rectifier, as I am assuming that you need 12 volts DC.
put a resistance in one of the wire connecting.....put around 2 to 3 ohm resistance to obtain 3 v fron 6 v.....
Yes, you would use step down transformer.
If 12 volts DC then you buy an inverter with the desired wattage rating. If 12 volts AC you would need a step-up transformer of the proper rating.
Answer . Probably not much because 6 Volts is not enough to power a 12 Volt coil
For an AC voltage you would use a 4:1 step-down transformer rated adequately for the necessary power dissipation. For a DC voltage you would use a solid-state voltage regula…tor or a two-resistor voltage divider (having a ratio of 3:1) and taking the output voltage from between the two.
Change the trailer light bulbs to 24 volts and supply a 24 volt source to power them, in that order.
How you can pass electricity 20 volt and 25 amp from converting 12 volt 1 amp adopter to 20 volt and 25 amp?
A 1-amp adaptor can not be used for equipment that draws more than 1 amp. It is not clear from the question which part of your system is 12 v and which is 20 v.
