Another Megasquirt Question

Guys could somebody explain the reasoning used in the enclosed drawing taken from the MS site ?

There is a 2A fuse shown protecting the circuit which comes from pin 28 of the board.On the load side of this fuse there is are 2 - 5A fuses protecting the left and right bank fuel injector circuits.There is also another 2A fuse in the FIdle solenoid circuit.
This doesn't make sense to me as the downstream fuses should never be larger than the one which is feeding them.Any comments ?

Simple, the wire simply feeds all the stuff, MS box, Fidle and injectors. It is not fed from the box it feeds the box itself, i.e. there are no serially connected fuses. :wink:

Thanks Mats. I was looking at things backwards :evil: I think I've inhaled to many lead solder fumes :roll: I completely overlooked the fact that this is the power INPUT from the "Main Relay" - can I offer my services to re-wire your home ?
