Early Ford V-8 Club Forum

FORUM RULES: Users agree to these Rules when using Forum.

The site administrator reserves the right to change the terms and conditions of the user agreement without prior notice to the user. It is the responsibility of the user to regularly review the terms of this agreement.

The user agrees to the following terms:

  1. All information that you provide to us for your membership is correct.
  2. You will not use your membership to spam, harrass, or exploit other members in any way.
  3. Vulgar, Abusive, Racist and Sexist Language will not be tolerated.
  4. Commercial-type sales postings will not be allowed.
  5. No mass posting or flooding of the boards is allowed.
  6. No Advertising of parts or cars; no Ebay or business/commercial ads (please use the "Classified" for ads Wanted or For Sale).
  7. VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
  8. EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

    http://donclink.com/deuce_75_1/images/dscn2950.jpg

    Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)
  9. HOW DO I SHOW MY EMAIL ADDRESS ALONG WITH MY USERNAME? You can LogIn on the Forum, and select PREFERENCES. On this page Members can add optional information such as their City,State, Country; Occupation; Hobbies: list a Homepage; list AOL Instant Messanger Handle; Signature; "Make Email Address viewable to others;" and even change the number of Default Topics shown on a page. WHEN others click on your profile, they will see this information.

One fact with Fords is that often there are often differences that are not "universal", but my references show that the horn relay was added to trucks in 1948, and the six volt version, 7RA-13853, was then installed thru the 1955 model year. If a truck doesn't have a relay, it is probably not a "deluxe" model, and some standard models apparently didn't get one after 1947. If not, I'd install a relay, as they are less than $20, and will preserve that high current system.

Fred, sounds like that should work. Run the wires as supereal mentioned in his first post and you should be good to go.

Supereal, I'm learning working on these old trucks that nothing is set in stone. I think the assembly plants utilized what parts that were on hand left over from older models. For instance my truck, an early 1949 assembled at Kansas City, has the same cowl to fender seal stapled to the flange of the fender as the 42-47 trucks instead of the foam seal normally used. So maybe the Kansas City plant had some older horns left over also? Mark

I've parted probably 6-8 F-series from F-1's to a F-4 and I've only had relays on the 51-52's with the hood mounted horns. And it was mounted near the starter relay ( V8 ) None of the single horns in front of the radiator had relays. I have also found single wire horns and dual wire horns on 48-50's. THese all had factory wiring and not all hacked up.
The 48-54 and 48-55 parts catalogs show a relay with a tan cover, but if you look at the wiring pic in the catalog, they don't show a relay in that pic until 1951.
On page 276 of the shop manual it states " Deluxe trucks are equipped with a pair of tuned horns controlled by means of a relay" Now the deluxe series of trucks did not appear until 1951. THe accessory trumpet dual horn kits had a relay. I am inclined by what I've seen over the years and the various parts catalogs and the shop manual, that trucks with single horns (48-50 ) did not have a relay. 51 and up did. I did not consult my 48-56 series parts catalogs as they were first printed in 1964 and were sort of a compilation and final issue that year. They are riddled with lots of mistakes and omissions and are a joke. I did Ford parts for 30+ years and have run into tons of mistakes in catalogs. Ford finds thier mistakes in catalogs from the people at the dealer level.
If you want to put a relay in, go ahead as it's added insurance, but if you're doing a 100 point resto, I say no.

Here is a link to the wiring diagram and schematic for your 49 pickup. It does not show a horn relay being used.

I haven't seen a truck with two horns without a relay. The single horns usually had two wires, one to the battery source, and the other to the horn button, which provides ground. Horns draw heavy current, and two need the relay. Much Ford literature says car horn relays began in 1939, but I have seen them on earlier models. The '38 had them, but the '37 did not. In looking at wiring diagrams, I agree that one horn trucks did not have a relay. I stand corrected.

One mistake in over 5,000 posts is a pretty good record. I wish that I was that accurate.

No, Tom. My mistakes are one heck of a lot higher than that. As frequent posters, you and I are certainly aware that trying to diagnose problems at a distance is usually a 50/50 proposition, at best. My dad used to say it was "like trying to judge a pig in a barrel". At our shop, we see plenty of jobs that perplexed others, including some dealers. Even with the OBD scans, some elude conventional diagnosis. We are headed to an era where vehicles will be plugged into a master computer back at the factory, and a list of repairs will emerge. The days of Gus Wilson and the Model Garage are long gone! Bob S.

Bob, have you ever thought of what is going to happen to these vehicles as they approach 25 years?

A neighbor had to scr*p a very nice 1993 Cadillac because the ECM was bad and the shop could not find one in the scr*p yard or find any one to repair it. My son had to hunt all over the US for the module that controls the climate control in his 1997 Mark VII. It took 3 months to find one.

What is going to happen to all of these hybrids when the batteries die?

Chrysler just recalled a bunch of cars because the computer module in the head rest may malfunction in a collision. Why they need a computer module in the head rest is beyond my comprehension.

Tom, nothing much surprises me regarding newer cars. The trend toward muiltiplexing to save wiring is a nightmare. Various components are linked by a common "bus", and are activated by digital command. Trying to diagnose these is bad enough, but many manufacturers have made the information "proprietary" requiring a fee to non dealers. We use ECM rebuilders for replacements, as the salvage yards around here don't have any. If the problem that killed the original ECM isn't found and fixed, the replacement will be turned into a paperweight as soon as it is plugged in. Chrysler has blamed the Japanese tsunami for the defective chips. They are used to position the headrest in the event the airbag system detects a crash. Frankly, I am not a Chrysler fan, as we see way too many of their vehicles in our shop. Our shop truck, an '07 Dodge, has already required replacement of most of the front end parts, including the wheel bearings. If Fiat doen't get their quality problems fixed, they are headed for big trouble. They are resisting the recall of the Jeeps because the gas tank mimics the same location that made the Ford Pinto a death trap. I think the answer to your question is that none of today's cars will be here, or fondly remembered in 25 years. Of course, that goes for many of us, as well!
