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.
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:

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!)

For some reason I think I have charging issues on my 40.At idle i am getting about 6.24 at battery.At a much higher RPM say 1500 to 2000 I still am getting around 6.20 to 6.30 at battery.I was thinking I should get around at least say 7.00 or more at high RPM?I have new wiring,regulator and I had generator checked and they said it was good?What else is there to check?i am not getting a reading in the green on my battery gauge either at say 60 mph?

Make sure all your grounds are good and clean. Especially the one from the firewall to the motor.

You are correct, at higher RPM should be about 7.2 volt.

I have read that a new, out-of-the-box, voltage regulator may or may not provide an accurate charging voltage. It may need to be adjusted. That is best done by an electrical shop with experience and proper gauges.

Edit: re-reading your post, you said at higher RPM measured 6.2-6.3 volt. That is just battery voltage. Sounds like it is not charging at all. That could be a bad regulator. But I'm quickly getting over my head now, so wait for replies from others with more knowledge. Best advice will come from Professor TomO.

Jay,I stand corrected.I am seeing around 6.40 to no more than 6.50 at very high RPM at battery.

I had another good generator and switched out and I believe it is just as bad or worse.At very high RPM I am not getting but around 6.24 to 6.32.seems to be not charging at all.Now I have fully charged battery with a charger,does this have anything to do with not charging when car is running.What I am saying is battery has a totally full charge on it now?I think it is pretty clear I have a regulator problem?

I tryed this.Is this good or bad to do this.Problem is I went a little to far because my battery gauge at 60 MPH is showing at the red mark?I figured this is not good!

Do not try to adjust the voltage on your voltage regulator yourself. You need preclusion instruments to do this job.

I think that your problem is caused by corrosion on the contact points of the cutout in the regulator.

Try: Connect your voltmeter to the BAT terminal of the voltage regulator, increase the rpm to about 1200 rpm and read the voltage. It should be around 7V.

If it is not, try connecting a jumper between field terminal and the armature terminal for a short while while reading the meter. Do not leave the jumper connected more than 1 minute or you can fry your generator. If it is around 7V your cutout points need cleaning.

Disconnect the battery, take the cover off of the voltage regulator and try spraying an electrical cleaner on the contacts of the cutout (the relay at the BAT terminal). Reconnect the battery and repeat the first test to see if that cured your problem. If not, disconnect the battery and use a fine (320 or F) emery paper. Fold a thin strip in half so that there is grit on both sides and draw it through the contacts. This should clean any corrosion off of the contacts.

Put the cover back on the regulator and reconnect the battery. Start the car and check the voltage. If it is not around 7V, find a generator repair shop near you and bring the generator and regulator there to have it checked out.

Thanks ,Tom.this has been a long going issue with this car ever since I had it.I don't think I have ever seen say over 7 at high idle.I t just always seems like just charging enough to keep up!I checked like you said at voltage regulator high idle and I am only getting around 6.40?Dang maybe I have two generators bad?I do have an extra ground wire run from generator to regulator mount screw,is this OK?I cranked my old 52 truck up and at high idle I am seeing 7.50 at battery/I have never seen that on my 40?

The cutout relay should pick between 6.5V-7.0V from the generator. This usually happens above 1,000rpm.

Having a grounding wire from the generator case to the mounting of the regulator will not hurt anything.

did you
polarize the regulator ?
to test the charging system. you could disconnect the regulator,
use a meter , one lead to the ARM terminal and one to ground,
now with engine running ground the field terminal for a split second and see if it charges higher,
if it does you have a regulator problem, or other issues,
never go by the dash gauge, buy a good meter, for testing
if it does not you have a generator problem
how are the brushes in the gen, are they arcing, ? short, dirty , comuntator corroded,
hope this helps, lease supply more information,, which helps us to diagnose
hope this helps, 37 Ragtopman

if you were to take the fan belt off you could motorize the generator, to see if the generator spins
[ TAKE CARE ] BECAREFULL,,,
take a lead from the battery to the arm terminal, use a heavy jumper lead, 10 gauge or more,
if it turns slowly the generator need to be cleaned or rebuilt, if it spins fast it sould be ok,

if you were to send both items to CERTIFIED AUTO in OHIO, they will check and repair,
and set it up to charge correctlly ask JEFF ot EARL
