My friend and I have successfully completed the first half of our project to manually control current output of an 85 amp alternator.
To achieve this we have removed the manufacturers regulator and
supplied current to the field via a voltage controller and a 5k pot plus a couple of resistors (and capacitors etc for noise suppression).
Everything good so far, The system is able to dial in current to the field and we bring the volts up to around 14.4v with the pot.
We would appreciate advice as to how to proceed with the next stage.
The current generated is used to maintain charge in our boats 12v battery bank. When any drain is put on the bank of course the loss is shown as a drop on the volt meter and vice versa when any appliance is turned off. Is there a way of varying the current supplied to the field to constantly hold the voltage at the original 14.4 volts? We have found that the alternator starts charging at around 2 volts
input to the field and reaches maximum output with 11.5v @ 6 amps
As you can see I have only slight understanding of what we have done as all the design has been done by my mate and I have just
put components together.Would really appreciate any advice as
to how to achieve this self-regulating system if it possible to do
relatively simply.
