[Mgs] Fuses

Highly unlikely that an automotive fuse would say '32v' where the 'v' means 
'volts', if that is really what it does read then it almost certainly is 
some kind of part number.  All bar one of the MGB fuses were originally 17 
amp rated, 35 amp blow, so a fuse will often read that i.e. 17/35.  The odd 
one out is a 500mA fuse for the sequential seat-belt circuit.  These are how 
the cars came out of the factory, you could have anything in-situ now.

Amps is amps, the voltage in the circuit is irrelevant in that 15 amps in a 
circuit designed to work at 12v is exactly the same current as 15 amps in a 
circuit designed to work at 120v, 1200v or any other voltage.  Of course, if 
you apply 32v to a circuit designed to work at 12v, then you will get nearly 
three times the current flowing.
