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.

1940 coupe with a 48 engine.
What would cause a generator to "motor" with enough force to turn the engine over??

In order for the generator to motor, voltage has to be applied to the Field. With the motor not running, the cutout removes all Field voltage, so that the generator will not motor. If you have voltage at the Field terminal on the side of the generator, either you voltage regulator is bad or you have a wiring error.

Has been fine for about three years.Even with the wire off of the small stud on the side it still motors, enough to turn the engine over.
I have a thread going on the Barn but I thought I'd pick some brains over here.

should be two studs on side of generator case--one is field and second is a ground, rear stud is armature

Remove the generator belt until you find the problem to prevent damage to the generator. leave the ignition switch off.

If the generator motors as soon as you connect the battery:

Check each terminal of the voltage regulator. The only one that should have voltage is the BAT terminal. If any of the other terminals have voltage, the voltage regulator is bad.

If the generator does not motor, turn on the ignition switch to see if that makes it motor. If it does, you have a wiring error or short between the ignition wire and the generator wiring.

Alanwoodieman, the 1939 and 1940 Ford generators did not have the ground stud. They relied on the case ground at the generator and voltage regulator end.

Your generator may have been damaged by the wiring error.

said he had a 1948 motor actually and an engine! two studs off generator. motors are externally powered, engines are internally powered--at least that is what the NAVY taught me.

I had the generator in my 1940 Ford "motor" about 15 years ago.

I had just installed it after purchasing it from a reputable vintage car parts place.

I had never heard of polarizing a generator, but after researching it, this seemed to be the problem.

After polarizing it, it never did it again.
