I looked at the "wiki" for my first time ever.

There was a high-lighted "link" that said "diesel tech articles" ; I clicked on it and, instead of diesel technical articles, it took me to some site selling cable TV or somesuch.

I tried it a second time and got the same results.

It is not the link in the list at left, but the one near the bottom of the paragraph of information.

 

I just tried it and it worked correctly for me.....I have no idea why it didn't when you tried it.....
