Interest in NB alternator circuit board?
#21
I needed to get this going to get my car running. With the help of Eagle software and their freeware offer, PCB to Gcode I was able to mill the PBC on a CNC mill I got a year and a half ago on CL.
I tested this out, the addition of the trim pot is brilliant! I used a 20 turn 1-100Kohm pot, you can dial the cutoff point pretty much wherever you want it. On bench test it's set to drop at 14.35V and it drops to effectively 0.
This works great. I'm stoked!

@WestfieldMX5, Thank you for the circuit, there is a need of trimming and alignment for the circuit but this is certainly worth my time. One thing however, whenever you’re charging batteries, one should always make sure that the power source being utilized is constant current source and the voltage has to be carefully adjusted so that the battery being charged doesn’t draw more current than the ratings. I believe that was the issue which has been addressed but there is also a need to avoid such issues altogether by a bit of care. The circuit for the alternator is all good. Reverse protection between power and ground will be a plus in this circuit which I’ll try to edit and upload.
