[s-cars] individual fused coils

[Paul Gailus]

Brian, 

I'd recommend using 5 amp individual fuses, although you could probably go as low as 3 amps and still be OK.

The rating of this downstream fuse must be small enough that a short will blow this fuse but leave the existing 15A upstream fuse fully intact. This will depend on the "selectivity ratio" of the particular fuses that are used, but a 5A fuse should provide enough margin.

The other more obvious constraint is that the 5 individual fuses each need to be at least 3A to support the same total average current as the existing 15A fuse.

-Paul
