Am I on the right track here? I'm designing a split front/rear battery pack with a contactor on the positive leg of each for redundancy. I had a thought of adding a relay to the setup of the front contactor that would interface with the accessory leg of the contactor to ensure that the rear contactor only activates if power is being supplied to the coil and the accessory leg was closed. Said the other way around, if the accessory leg is closed but power wasn't applied (stuck contactor) at least the rear contactor wouldn't latch. Thoughts?
