My 1995 SPI seems to have an extra fuse box hanging behind the throttle body.  I wonder if it is something to do with the aftermarket immobiliser which was fitted many years ago?  Any thoughts?

Someone that knows their stuff better than me will be along shortly I'm sure, but as far as I'm aware the early spi cars had a 4 fuse box as seen in your picture, this meant a lot of in line fuses in the loom itself. To resolve this they later, as per my car, went to a 24 fuse fox mounted in the same place.  I'm wondering whether a previous owner has done away with the in line fuses and replaced them with the blade fuse box you mention.  Thing to do would be to compare the wire colours into the blade fuses with the wiring diagrams for spi models found in the link below, this will give you your answer as to what's going through it.

I ended up doing this to my spi too - what they've done is replaced the various in-line fuses (complete with fiddly and often unreliable holders) with a separate fusebox.  Not a terrible idea, if its done properly.  You can still check what fuse is what from the colours of the wires (the handbook had a section about this if I remember correctly).  Its a shame you now have a mix of glass original fuses and modern blade fuses - make sure you've got spares of both!

Line fuse replacement would be my guess too.

 

Looking at the wiring diagram & comparing wire colours should confirm. The other question is are all the fuses of the correct rating. Glass fuses show the blow current - blades show how much current they are designed to carry continuously.
