Title: Cold Light
Post by: R. Dave Carr on November 28, 2007, 10:04:02 AM
Does anyone know how the "cold" light in the dash of my '66 300 works?  What turns it on and off?

Ahh it's run by a switch?(http://www.moparfins.com/forum/smileys/smiley25.gif) (http://www.moparfins.com/forum/smileys/smiley36.gif) (http://www.moparfins.com/forum/smileys/smiley36.gif) (http://www.moparfins.com/forum/smileys/smiley36.gif)
 
On the water pump housing there is a two pole sending unit with two wires.  It's on the right side by the Alternator.  One side is cold, the other is hot.  I assume the cold light is not working, and hopefully, you haven't seen the Hot.
 
To test the light curcuit, you may ground the wires at the sending unit to see if the lights work from that point.  If they don't. . .You know, the sending unit is bad.

Because with all the skin I left under that @#$%&$! dash, I want all the pretty lights to work!  Seriously, it worked for a few days, and then quit.

Obviously, I have the same light and it too does not work. I noticed it in the cluster but never thought to check it's function. I will be getting into the cluster this winter for a few other bulb replacements such as high beam indicator and signal indicator. At what temp is the cold temp light supposed to trigger? Is it an extreme cold or just say room temperature?

 It will go on in the summer, just not as long as winter.  Probably 150 160 it will go out.
 
Other places to check. . . The cluster has a PC board on the back. . .check the traces.  You may have to solder a jumper.  Make sure you have a good socket for the bulb and  there is continunity from the sending unit to the dash.  Also check to be sure there is no oxidation on the conncetion points on the board.  A touch of vasoline can't hurt

Is this the sending unit you're talking about?   
      (http://www.moparfins.com/forum/attachments/52/TS-15.jpg)  
                                           
The terminals are at say 12 o'clock and 3 o'clock. If so, it is Blue Streak pt# TS-15 and readily available. I have not checked my sender but suspect it to be the problem. I will order up one anyhow and throw it on the pile for the winter.

It looks like that yes.  As long as the application is correct, it should work
Title: Cold Light
Post by: R. Dave Carr on November 28, 2007, 03:23:32 PM
TS15 is correct, I just ordered one.  I grounded out the plug and made the light come on, so I know the cluster is ok.

That reminds me of a kind of funny story, my Dad used to sit in the car (65 Newport and 72 Newport)and let it idle till the cold light went out. Summer or winter I guess he thought it wasn't ready to go till that cold light went out.
He cracked me up sometimes. Ahhhhh memories!!

The guy that had my Chrysler before me put in temp,volt and oil pressure gagues and must have put in the sensor that came with them so my cold light doesn't work. (http://www.moparfins.com/forum/smileys/smiley6.gif)ardog2007-11-29 03:39:15

I believe 68 was the last year they used the Hot/cold light in c-bodies.
 
I was happy to see this thread because when I get the motor/trany in the wagon I want mine to work properly too.

What the heck do you expect!  He's 78 years old!  He sent me a bypass hose for an LA instead of a Magnum.  All he heard was 92 and Magnum.  He's tired. (After 28 years of selling to me who wouldn't be (http://www.moparfins.com/forum/smileys/smiley2.gif))
 
But YOU! could be a great survice to these thugs and start selling them the parts they can never find.  And please.  Don't tell me it's not in the computer.

I checked around and the "cold' light was in Chryslers only up to 1973.IIRC< Dodge and Plymouth did not get the cold light-just the "HOT" light or guages if equipped depending on year and model
All Formals (1974-1978) got temp guages and a red dot light when hot.

I wish I had seen this earlier Brian. 
 
I remember the "cold" light in my '66 NYer well.  I only ever saw the "hot" light once thankfully. 
 
What's interesting is there were two empty spots on that car's dash curcuit board...  made for turn-signal indicators for a car without the lighting package!  I spun a couple of PR194's in and they worked WITH the fender ornaments. 
 
My '68 NYer had both and both worked so I disregarded this as a fluke.  I dunno...

Hey Maffew!!
My 66 has only fender turn signal indicators none in the dash.
Dan Cluely (a guy on here) told me his 65 300 was the same way but he put lights in his too,but told  me I'd need some little black plastic thingies that hold the bulbs in the dash. I guess you put the bulbs in the plasic dealies then put them in the dash.???????

Those thingies are bulb sockets and you can still buy them.

Yeah, but you better have a part number, cause if you try to describe them to the parts guy at the dealer, they look at you like you've got a third eye in the middle of your forehead.  (or maybe my local Chrysler dealer just sucks. (http://www.moparfins.com/forum/smileys/smiley5.gif) )
 
Arlen, I should have some extras, so remind me to check if you want a couple.

Go to the wreckers....they used those in most Ma' Mopar products up into the 90's.
 
I have a big jar full of them, I always pocket a few when I hit the wreckers....(http://www.moparfins.com/forum/smileys/smiley9.gif)

Regarding why some 65's and 66's had them in the dash and others didn't?  I got the answer from a Mopar grey beard years ago when I discovered the "non-functioning" signals in the speedo of my 66 T&C.
 
The speedo clusters were all the same, and the signal holes were simply covered in black tape on the assembly line.  My 66 T&C still had the black tape over the holes when I put the bulbs and sockets in.
 
Now, in Ma Mopars wierd way, contemporary Furys and Monacos got the fender mounted units, but they were small and dim enough that they were not able to be seen during the day, and therefore the in dash signal bulbs were left in....  go figure!(http://moparfins.com/forum/smileys/smiley5.gif)

Oh, and yes, the temp sender for Cold and Hot light equipped cars is still available, I just bought one last year too. That sender was used in a multitude of cars. 
 
Ground the wires to the block to see if the bulbs work first, then check the bulbs in the dash, and then replace the sender last.  That is the order of operations for trouble shooting that issue.

I think they fixed the problem by 69, the Dodges for 66 were very small little triangles....  however, I could be wrong, but mine don't show up at all during the day!
