(Still waiting for J4 screw terminals to arrive - this is what connects back to the CMRI node)
...
- LED1 electrically does not have a polarity as it voltage is AC and swings positive and negative
Wiring
2 ea of 12 inch 18 ga wires
- Pad closest to diode get a fork terminal crimped at end
- Pad closest to PTC resistor gets a male spade connector crimped at end
- Single wire through current sense transformer is 1.5" 18ga
