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!)

You have an aftermarket electric fuel gauge or one from a non-Ford make. They usually are the resistance type where there is a variable resister in the tank unit and a bi-metal strip in the gauge unit that heats up and bends. The bending action moves the needle. This type can work with both POS and NEG grounding depending upon the connections.

Your best bet is to find a 1936 Ford gauge cluster and adapt it to your 1934 Ford.

To change the polarity of the car, you will have to have a new coil and cutout for NEG ground and polarize the generator. If you have any accessories, their polarity needs must be accommodated.

The gauge will only work with neg earth, I get no reading when pos earth/

Are you sure the gauge is polarity sensitive? The early Ford types were originally vibrating points type where the current was on and off as it heated a bimetal strip whose tension was a function of the float and then pointer movement. Some repro senders used a variable resistance (set by the float) to maintain a variable current. Neither the points nor the resistor cared which direction the electrons flowed.

Can you not just reverse the leads on the gauge? I installed a 6V electric fuel pump on my '46 coupe, and the instructions for use in a POS ground system, was RED to ground and BLACK to power.

Hi
How difficult is it to change polarity from Positive earth to negative earth on a 34 Ford. I am having trouble getting hold of a 6v positive earth fuel gauge. I have a 6v neg earth gauge but it will not work on the pos earth system. I am thinking I would only need to change battery terminals, coil wires, and generator polarity. Is this correct?
