So I've seen many different incarnations of the fuseboxes in SPI's. There's a blade type, the 4 fuse type and inline ones mounted behind the air box. 

 

So my question is, what do these 4-5 inline fuses control? Mine is a 94 spi from Japan if that matters. 

 

ALso, is there ANOTHER fuse box behind the dash?

See in the FAQs Electrical section if the wiring colours match up? so you can identify the circuit

On my spi shell car yes there are inline fuses (for the headlights)behind the speedo binnacle, you can get to them in between the heater and steering column

The photo shows "flying glass fuses"

I had 7 behind the Airfilter.

4 behind the instrument panel  which control the mains to the front headlights..

4 in the little black box (fixed to the fire wall)

 

They were glass.

Changed to large fuse box with blade fuses.

 

I could not find anything about fuses in Japanes Minis.

The 1994 Japanese Cooper should have (at least mine does) the standard 4 fuse box on the bulkhead and all the other standard in line fuses. So, everything should match the UK Mini. The exception is for the fuses and relays for the air conditioning. I have not been able to find specific diagrams for that. However, the available 1997 on Japanese Mini wiring diagrams seem to shed some light on the previous models in regard to the air conditioning and the catalytic overheat buzzer. Apparently, the wheel was not reinvented for the newer models.

@xrocketengineer The fuse that keeps blowing I THINK is the auxiliary cooling fan switch. If it's faulty, would that cause the fuse to blow/cut engine? The car will run fine until it gets warmish, then the car will stall and the 15a fuse is blown. I replace the fuse and it drives/runs fine. 

 

Can I test the auxiliary cooling fan switch?

The radiator auxiliary fan switch at the bottom of the radiator only controls the relay coil. That is fed from fuse F5-6 a 25A fuse on the fuse box with a light green/orange wire that goes to the relay coil. It comes out on the other side of the relay coil as a light green/white wire that goes to the switch on the radiator. The power to relay contacts comes line fuse LF5 15A fuse with a purple wire coming out and going to the relay and goes out to the motor on black/green wire.

If the car stalls and the fuse blows there has to be an intermittent short to ground/earth on either the purple wire or the black/green wire. That fuse is only for the fan, the car should run with it blown, unless somebody did some creative rewiring.

Other unlikely possibilities would be an intermittent short on the fan motor or a dirty/corroded connection on the fuse holder.

The fan switch is just an innocent bystander. That is my take.
