😳😳😳Relays per Hot Rod magazine

Dear Larry,

        Perhaps the title of the column: "Wrenching at Random" provides a clue.  I suggest that "Writing at Random" is more accurate?

A lot of articles in that and similar magazine just continue to amaze me. In your attachment note  01  talks about using 87a for connecting to an extra horn. That would work out great, if you wanted the second horn on all the time... When you hit the horn button the other horn comes on and the second horn goes quiet. I suppose you could wire in a second relay to 87a of  the first relay which will then be activated when the horn button is not pushed, with the second horn connected to 87a...  It takes me less than 20 mins to read those magazines, they do have nice pictures sometimes. No wonder Car Craft went under.

I guess it depends on the manufacturer (china?) of the relay, I've seen both normal open contacts labeled as 87 and 87a. And I've seen 87b being used also as NC contact.

 My comments were built around a standard relay; the design that will be found in most automotive applications. I imagine there are specific purpose variants in the relay world that I haven’t seen. 

 Staying with the article, the relay with its pictorial imprinted on it is clearly a standard 87 and 87a relay, each respectively being normally open and normally closed. 

 The author should have just stuck to a tutorial on crimping connectors. By attempting to gloss over relay function,  his inaccuracies will undoubtably cause more problems than solutions.

when an author uses "colorful" terms in leu of proper terminology, I assume the info is for intertanment only.
