How to connect an alternator p. Load a battery published by Manual-Mecanica
Good afternoon.

First of all I present myself, I am new in this forum and my knowledge of mechanics are quite scarce.

The reason for my query is as follows:
I am manufacturing a device that, using a bicycle to move a car alternator manages to load a battery.
I have the structural part, with a pulley that goes from the rear tire of a bike on a support to a car alternator, I get a pedaling cadence of 55 pedaling per minute to transmit to the alternator about 2100 revolutions per minute. I think that is enough. It's right?

My question comes when connecting the alternator to the car battery. I see a screw that must be a dough, another that looks like the positive and a file with a phase.
What would be the connection scheme?
Could you incorporate a voltmeter to know the load level?
What section are the cables to connect to the battery?

Thank you, any clarification is well received.

Greetings

If you want you to help you, you must specify that vehicle is the alternator. For an alternator to work, it needs to make land in the structure by means of the car, the load or positive line is the one that has a nut and is isolated with a plastic washer in the base. If it is with a built -in regulator, you need to connect in the lines that are marked l and s is the voltage and the l is a pilot light. This pilot light feeds with positive voltage and makes the ground when connecting to the alternator terminal and save when it begins to load. The positive is to feed the regulator although there are alternators that bring it but it is not connected and the connection of the pilot light is always more essential than the battery lines because without the pilot light does not work the alternator's voltage regulator. They usually bring these letters but would know how yours is to see how to connect it

Hey but they sell battery chargers and are not expensive, apart from the amperage is the important one in this house if with the bike I send 2 ampers hours, you have to pedaling about 10 hours for 20 amps and the batteries are 55 hahahaha

Hi, I like the original ideas, curious invention. Once the alternator is excited, with 2000r. If while the battery is loaded, you have no consumption, with a 5 mm cable I think you will have enough, the control light with a tiny cable is enough, the fuse would put it from 40a. If the alternator has only one Fauston output, it is assumed that it carries the incorporated regulator and the attached scheme would have to work well. Good luck and go ahead! You will tell us the result. Greetings

Holla the idea is interesting there are alternators that can work at 1800RPM but your problem will be to maintain that revolutions as tired as possible, I hope you have good lucky legs.
