While researching my problem I found an article that doesn't make since to me. Is this statement right?

A bad ground can also keep you scratching your head. Typically, the distributor grounds itself to the engine when installed. But, if the ground from the engine to the battery is making a good connection, ignition spark will be none existent. To test for a good ground, a jumper wire can be attached to the distributor by connecting it anywhere on the housing and running it to the negative side of the battery.

Shouldn't that be if the ground from the engine to the battery is not making a good connection???
