Wind powered generater

[Allan]

I have a 22ft Etap which will be going out on a mooring. I have just found an old wind powered generater which came off an old boat. I would like to fit this to the boat when I am not there, to keep the battery charged. Can anyone tell me how to test it and what type of regulator to use? I dont want to overcharge the battery. I have a 75amp/hr deep cycle battery.

take the blade off and run it with a drill, dont go mad with the speed though.
Just measure the voltage at the end of the wires.
With out a model number or make i could not say if you need a regulator but my aero 2 gen thats a 2amp max output does not need a regulator

A variation on Steve 28 a voltmeter will not tell you as much info as an ampmeter with the generator trying to charge your boat battery or even car battery. Any current under 1 amp should not need a regulator. If you need a regulator try one of the regs intended for a solar panel. This assuming that the generator has permanent magnet with no field coil. (Just 2 wires emerging.) Also you will feel a resistance to turning which increases and decreases through the turnas you rotate by hand) If it has a field coil (3 or 4 wires) then you will need to use an engine alternator type regulator and lots of experimenting. NB the negative wire may be replaced by a metal mounting connection just to confuse you. Good luck ole will

Aerogen recommend a regulator for the Aerogen 2 , which is perfectly capable of overcharging batteries and ruining them if you don't fit one. I had to buy two new batteries last year because the regulator on our Aerogen4 was u/s.

Aerogen 4 has a regulator connected to a large dump resistor which gets hot and hums when it is dumping current - which ours has to do regularly.
