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.

Fred: To answer the question, we have to know what year vehicle you have, and whether it is a 2 or 3 brush generator, and did the system function properly before the problem arose? When you say "regulator", is it an actual 2 brush type on the firewall or the round cutout on the 3 brush generator? If it is a 2 brush type, it is likely the generator output is insufficient to cause the cutout relay to close. This can be due to a number of problems stemming from the condition of the generator itself, or can be caused by a poor generator ground, or a battery with a high resistance cell. Sometimes it is just a glazed or slack drive belt, or one poor connection.

sounds like the reg needs adjusting or replacing, I like to have the gen and reg set up by my generator rebuilder

Thanks for the info, Fred. I'm curious how the regulator was tested and pronounced OK. We often find an incorrect regulator on a vehicle, or one that has been "adjusted" by some trial and error. It is also possible that a perfectly good regulator doesn't work properly because it isn't grounded. Some regulators have a separate ground lug, while others depend on a metal ferrule in one of the rubber mounting feet to provide a ground, but failure to remove the paint or dirt, etc, to make a good body contact defeats the purpose. Same is true with the engine ground strap to the body, which sometimes is missing altogether. We do a lot of auto electric at our shop, and it is safe to say that poor grounds are the cause of the majority of problems. It takes some detective work with a good volt/ohmmeter to pin down these types of causes.

Hope so, Fred. There are not many shops today that know what a generator is, or how to fix it. Turning a commutator and undercutting the mica has become a lost art. Today, we are dealing, more and more, with charging systems that use the ECM to regulate charging. Given some TLC, the generator/regulator set up certainly served well from '39 on into the 60's. As vehicles are loaded with accessories, I'm betting the 24 or48 volts will become the norm, as they have in military use.

Could it have the wrong diameter pulley on it?

Using an ammeter to determine if a generator and regulator are working properly is an exercise in futility. The ammeter will just show the amount of current flow and the direction of the flow. When a battery is at full charge, there will be very little current flow, no matter what the engine RPMs are. A sulfated battery will also cause little current flow in the circuit, because it cannot accept more of a charge.

A volt meter connected across the battery will give you a better idea of the condition of the regulator and generator. With a 6Volt system, you should see about 7.2-7.6 Volts across the battery at 1500RPM with a generator and regulator that are working properly. Any reading out side of those specs will cause problems.
