Power first goes to circuit Board1
, where a light duty switch immediately activates a car type relay for the high current 36v motor supply. Also included is a delayed turn on of 3 secs, using a Picaxe 08M. The delay is to protect the digital ampmeter from the initial current surge to charge the capacitors. A small DPDT relay controls both the 18v Mosfet supply and the 12v isolated supply for the micros and Hall Effect Sensors.
