What is the purpose of this resistor network? Why not just use one resistor? or connect the cathode of RA93 diode directly to the mosfet drain (this mosfet is high side of the h-bridge).
It seems to me that pin 30 of the relay is connected to pin 87 through diode and the resistor network. I just am not able to figure out why? The diode is probably to preventing the circuit in case someone plugs in the battery terminals backwards, is this right?
Alternate schematic (by @Transistor) emphasising bulk capacitor and relay bypass of soft-start. Purpose of D3 is unclear. Operator to review.
