I want to include a precharge resistor in parallel with my contactor to charge up the capacitors on my motor controller. This way, there won't be a large in-rush current through the contactor when I close it.
The problem I'm having is that the motor controller is powering on from the precharge circuit, and because of that, the capacitors are not charging up.
I'm using 1 kilohm for my precharge resistor. The steady-state voltage I see on the motor controller during precharge is 3V when I want it to reach about 48V.
Is there something I'm missing with my precharge circuit?
