I think this is a basic electronics question, but I can't easily think of a solution.
How do you limit current in a wire without dropping voltage?
So my application is I want a low current feed to the controller to do a precharge of the capacitor to 90% of pack voltage (its an option on the Curtis1244 controller).
If I jump the main contacter with something that limits current then that would allow it to precharge.
But if I just put a resistor in, it will sap most of the pack voltage and therefore the precharge wont reach 90%
