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!)

Okay, so I posted something on this previously, but now have a slighted different question.

I am installing a brakelighter third brake light and turn signal under my '36 Phaeton. As far as I can tell, I will need to install diodes in line for the brake and signal wires because of the double-filament bulbs. I am planning to put the brakelighter wiring in cloth conduit because I don't like the idea of multicolored wires running underneath, and well, why not.

Now here is the question, can anyone think of a reason why I should NOT also put the diodes in the same conduit? My thought is that it would protect them, and that they would be less likely to get disconnected. BUT, I know nothing about diodes other than what I have read on Wikipedia.

So, could the conduit cause problems? Fire hazard? Overheating, etc. I am guessing unlikely, but since there are a lot of much more experience folks on this thread, I thought I would pose the question.

Any thoughts welcome. Hopefully this simple project (which was supposed to last an hour and has now lasted weeks) will soon be over. By way of background, this all coincided with a short, and non-functioning turn signals that I finally (think) I have sorted with a new ground.

I'm thinking you won't need the diodes. I believe your car had double filament bulbs to begin with, regular headlights/tail lights and stop light. If you're going with LED's it may be different.

The brakelighter wiring diagram says to use diodes for installation with double filament bulbs. It is an LED third-brake light, so maybe that is the issue? It is honestly all greek to me.

I have installed a Brakelighter on 3 of my early Fords, no mention of diodes in the instructions, and non used. They have been functioning properly for years.

Interesting. Do you use as both turn signal and brake lights? Am I misreading the wiring instructions? I would rather not install them, but will if needed.

I wired as per instructions and have brake light and turn signal function.

I see two ways the third brake light could be wired: 1) would be to run a dedicated wire from the load side of the brake light switch to the 3rd brake light. 2) would involve a wire from the bright (brake) filament in each tail light to the 3rd brake light. This would require a diode in each wire to prevent backfeed into the signal system.

So option 1 is what i think is in the standard wiring instructions. I am confused as to why they would include the diode instructions to be used with dual filament bulbs. I guess I try it without and if it works move on. If it doesn't I can always try again.

I posted before I looked for the wiring instructions for the Brakelighter. It looks like someone has drawn the diodes in on your picture. The diodes are not included in the link I looked up.

The 3rd light has two separate sides to facilitate the signal function. Each side has a positive and negative connection. Just switch the pos/neg to reverse polarity.

here's a link to a better picture of the wiring diagram with the diodes [drawn in].

http://www.brakelighter.com/v/vspfiles/instructions/6-volt_positive_modified_wiring_diagram.jpg

notice that the turn signals are also drawn in. the diode on the brakelight keeps it from blinking. the diode on the turn signal keeps it from being a brake light. they [obviously] would not be needed if the brake light and turn signal light shared a common filament. leave the diode off the brake light and it will still be a brake light but will blink. leave it off the turn signal and it will still be turn signal but also another brake light.
but back to your question, i connected an IN4001 diode to a 6-volt brake light [and a battery] and held onto it. it does get hot but not to the point i had to let go. why don't you just connect a brake light and your diode in line to a battery, wait a few minutes and decide.
