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!)

In pulling together a 'road-trip' set of tools and back-up parts, including a heavy-duty set of jumper cables, it occurred to me that I was not fully conversant with the (hopefully not required) process for jump-starting my '47 6V pos grnd system with a more-than-likely-only-thing-available-at-the-worst-possible time 12V neg grnd system. Clearly one needs to protect the points as well as the voltage regulator - can anyone advise the correct process for this? And after the car is started, what concerns exist, if any, for the generator throwing heavy juice to the battery to recharge it?

I believe I know but have never read this anywhere nor performed or seen it performed before, so an endorsement of what is technically correct is greatly appreciated.

To jump start with a 12 volt battery put 12 volt positive (+) cable onto negative (-) cable on the 6 volt battery. Touch starter side of solenoid or starter post with other cable. Do this quickly and remove as soon as it starts. Works for me.

Think not about which is ground and which isn't. Just hook positive to positive and negative to negative, never positive to negative as has been suggested. Disconnect as soon as starts or cables will start to burn. Done it many times with no problems. I have a 12 volt jump starter in my trunk that I've used way too many times. (Have never been able to find a 6 volt one.) Works fine.

Henry is correct. I think Joe meant that, but got himself confused with the reversed polarity of the modern cars.

I think the only real danger is if both vehicles have conductive bumpers (such as metal) and they are touching each other. This can create a dead short, as one is + and the other car will be - at the surface of the bumper.

Thanks to all - I had been advised previously that connecting a 12V battery through the entire system by simply connecting batteries pos-pos and neg-neg (versus, for instance, connecting the negative end of the jumper cable to a head bolt and touch the positive to the stud on the starter) is likely to damage the voltage regulator and burn the points. Urban legend or is there any substance to this?

In all of my 12 volt jumps I've never suffered any such damage.

Steve,

Never connect a 6 volt and 12 volt battery or system together, the 6 volt battery may explode and you can damage the 6 volt components.

The correct hookup with a 12 volt jumper, is to connect the POS cable to a ground away from the battery, on the EFV-8 to be jumped and the NEG cable to the starter terminal. Make sure that the bumpers are not touching. Do NOT push the starter button as you can connect the 12 volts to your 6 volt system.

IMHO, the best way to start an EFV-8 with a dead battery, is to push it. The jumper cables are used when that is not an option.

Thanks to all who responded - I've got it down now should it become necessary.
