I did a dumb thing today working on fuse bus with master on.

Bus was shorted to ground.

Now no power to bus. Checked all fuses and circuit breaker; no joy.

Checked master relay at battery box. When turning mater on the relay engages.

I did notice a diode and resistor under the relay. The diode comes off the switch side of the relay then terminates through a resistor to ground. The resistor is broken. Does anyone know the ohms of this resistor and what this circuit is for? I do not think this is the problem. But i want to fix it.

I think I pop something near the generator.

I know I was stupid for not disconnecting the battery and working with the master on
