Quoted from jclocomotion:just need to work out the Locomotion ones
See the fuses mentioned here - they all appear to be fast blow:

Generally speaking, when a circuit requires a slow blow fuse it will be specifically stated. If there's no mention of slow blow or fast blow then fast blow is presumed.
Looking at the schematic of the Locomotion power board, those fuses all look like fast blow based on the circuit design.
Quoted from jclocomotion:yes seen that but normal what was confusing us as some elements need fast and some slow
To quote, he refers to "(Normal or Slo Blo)", so by Normal he means fast blow.
It looks like Zaccaria may have used higher value fast blow fuses (because they're cheaper) where the type of circuit might better call for using lower value slow blow fuses. Eg, you could probably use 1.0A to 1.25A slow blow fuses where the coils are instead of the 3 amp fast blow fuses as stated.
Quoted from jclocomotion:but will get a good few slo
Get quality slow blows that are spring/coil type. The cheap slow blows with the small looking solder spot in the middle of the straight fuse wire are not designed to take repeated high current surges so fail prematurely in solenoid circuits.
