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.

Last fall I had a total engine failure, as things were going wrong there was a lot of engine overheating, it blew the radiator as well as forcing water out under the radiator hoses. Now that we have a new engine installed, the temperature gauge reads on the high side even though the engine temp is normal. There is also a new temp sender in the cyl head and all connections are clean. Has anyone needed to recalibrate an electric temp gauge?

The King Seeley gauges are usually quite close to the condition that they are monitoring. It would help if you gave more information about your car.

What year is it?

Do you have 2 sending units, connected in series?

Is your car 6 volts or 12 volts?

Did you use teflon tape or pipe dope to seal the threads on the sender?

The car is a 1940 Mercury, there is one sender on the left bank. It has not been recently installed, it came with the replacement engine. I removed the attaching wire and filed the connections to make sure they had good contact. I guess my concern is that the gauge was forced into an extreme position when the engine blew and the gauge may need to be recalibrated, however I do not know if an electric gauge can be recalibrated.

A new or rebuilt engine will naturally run hotter until it is broken in. Also, the King Seeley gauges are not always exact but will give you a good benchmark. You should go out and buy a hand held temp gauge and check the temperatures on various parts of the engine with particular attention to the area on the heads where the original temp sensor is located. I wouldn't run thermostats until you have broken in the engine and you have a handle on the actual running temps then install 180 degree thermostats for the best running temps and efficiency.

Thanks for updating your question. I am guessing that you have used a reliable thermometer to check the coolant temperature. I like to use a candy thermometer sold in hardware stores. Just clip it into the radiator opening with the tip immersed in the coolant.

The gauge and the sending unit work as a pair and the current in the circuit causes the gauge needle to move. The original King-Seely sending units have a wire wound around a bi-metal strip that opens and closes a set of contacts. The needle move toward cold at maximum current and towards hot as the current decreases.

My feelings are that the sending unit is not working correctly. Check for continuity between the sh*ll of the sending unit and the head. Connect your test leads together to find the 0 ohms reading on a digital meter, and to zero the reading on an analog meter. Connect the meter leads between the sh*ll of the sending unit and the head. Any resistance here will lead to a higher temperature reading.

If your sending unit is properly grounded, the next thing I would do is replace the sending unit. Try to find a good used one, as some the replacement ones have a thermister inside instead of the contact point and bi-metal strips.

Chascwell - you never mentioned in reply to TomO's questions whether teflon tape or pipe dope were used to seal the threads on the sender. Please advise in that regard. Thanks in advance -

Steve

I think checking the resistance between the sh*ll of the sending unit and the cyl head is a good idea. I did not remove and reinstall this sending unit, but checking there is a good idea too.

Thanks for the replies.
