Hi to all, just finished a 16 pole/12 coil genny 32 1x2x.5 mag 12 coils/70 turns,current goes into the 12v batt at about110 to 120 rpm, moderate winds, got up this morning to find the inverter alarm on (overvoltage shutdown), i disc the turbine from the batt pack and connect it to a used automobile batt. when i checked the voltage of the batt pack it read 15.5v at around 11am i read it again and it was 12.36v. Question.... should the voltage drop so low so soon without a load ?
Another thing i've found out is that when the turbine is connected to the used 12v car batt the rpm drops to under 100rpm with about 3 to 4 amps into the batt,(seems like a good dump load ) and remain there for hours never increasing in rpm or amps
I have another large tractor batt 12 v with a dead cell i cut out the dead cell and now have a 10 v batt , when connected to the turbine it bubbles like a ,kettle, is there any harm in doing this ?
