August 23, 200719 yr comment_193475 If the max rating of the alternator is 40amps, your fuse should be rated above that (what is called the fusing factor). For electrcial fuse (eg 415V used on your power networks - I'm a protection engineer with a NSW electricity company) we use a factor of 1.5->2. Perhaps try 60amps fuse. you could probably get away with a 40amp as it is unlikely you are going to load the alternator right up to its limit. however if you do run 40amps through a 40amp fuse over time it will weaken an eventualy blow - when there isn't a genuine need for it to blow. Remeber the alternator is rated to 40amps, if you have a fault on the wiring it will deliver greatly in excess of 40amps and 60amp will clear the fault still quick enough. As to the size of the wire not sure? Anthony Report
