Go directly from the fuse panel, not from a victor. I am not quite sure but i think you should use a 20 or maybe 30 amp fuse. the 40 amp fuses are for the motors.
The phase b pins are used in if statements so that it adds to the counter if it is moving forward and subtracts when moving backward. You basically have to replace it with code that will just add to the counter whenever an interrupt is fired off.
Something like this should work:
Code:
void Encoder_3_Int_Handler(unsigned char state)
{
if(state == 1)
{
Encoder_3_Count += ENCODER_3_TICK_DELTA;
}
}
