it wont let me put photos p for some reason if anyone has an email i can email them a picture of it so they can look at it and help out cheers.

i duno how to post up pictures im new to this lol.

it isnt a custom job it was in the car when brought ill get a picture up soon of it.
every time it blows the car idles real high and the alternator charge light comes on and the car misses.

its a different fuse block to the picture you have but it is the engine management fuse. it will run sweet with it in and run rough with it blown.
as soon as we try rev the car up it blows the fuse. otherwise it will idol fine.

i had exactly the same problem i went off the manual and it was about a quater of a turn out i had to get a datsun mechanic to sort it out. got that all sorted but now have fuse problems can anyone help me?

hi everyone i have a problem with my datsun 1200 sedan i can start the car and it runs sweet as but after about 2 minutes of running it blows the engine management fuse and wont run right.
