RE: {Chrysler 300} 57 Chrysler Shop Manual

["Ron Waters" <ronbo97@xxxxxxxxxxx>]

The switch's ground completes the circuit when the switch is moved to the second or third position. If in the first (off) position, the circuit is completed by the A-post switch when the door is opened.

 

On the convertible, it appears that, according to the schematic I attached to my previous email, there is a jumper between the two posts in the back of the switch. So same behavior in either the second or third position. On the HT, the switch in the second position is the only way that the map light's circuit is completed. For the roof rail lights, the circuit is completed either by the switch or by the doors opening. Which makes sense.

hi Ron  The function , wiring colors and operation are the same 
Chrysler or Dodge , and the only change  to a convert is the courtesy light 
location on sides instead of roof .

The issue you describe is the yellow wires are mixed up . Why I say confusing . 

I had to go to house and think the first time , what is that three legged thing actually doing inside ? Think about it .., note a ground IN the switch too . 

So note which wires go where vs view of switch ( rear view I hope) I think You will find two yellow are swapped !

The thing that had me confused was that I thought that the lights grounded to the body. Nope. the yellow is the ground.

 

Also, not sure about Chrysler, but on Dodge, the map lamp switch is three position. On hardtop, the first position is off, second position is map light and third position is roof rail lights. But on convertible, it appears from the illustration that both the second and third position have exactly the same function: turns on both the map and pocket panel lights. Not sure why they did that. Hope I'm reading the illustration correctly.

hah — that switch has baffled many of us , note the ground symbol inside it . So when you turn on either lights it grounds  yellow at switch , either light alone . but when you turn off it jumps both yellows together so door switch lights both ! you can do that with dpdt toggle center off and a diode . either map or roof on  switch  , grounding roof grounds map by diode from yellow roof wire ,  grounding  roof at door ( when switch is off )  by door switch turns on both .

Convert they sub rear courtesy for roof . 

I copied this on 37 packard it had map and roof , but no door switches in 37 . added them , using mopar wire colors ! 

while on this pink feed is “on “ 12 v all the time , i have had 3-4 cars ( F) where it corrodes in driver kick panel plug , turns green . (12 +  dampness?) That means no roof lights

I do a scan out of the shop manual. Then I can make as many prints as I want. When one gets too wrinkled or marked up to be usable, I print off another.

 

The actual nature of my search was the difference in wiring for the map and pocket panel lights on the convertible vs the map and roof rail lights on the 2dr HT. In this case, my 59 Dodge convertible. I eventually found that info in the 58 Dodge shop manual. After scanning the schematic, I got a little fancy (see attachment).

Quite a while ago, when I was working on the wiring of my 300C, I took a photo of page 401 of my Chrysler Service Manual, made a 2ft x 3ft poster of it and hung it on the wall so I could see the diagram no matter where I was in the car. it is still there and I still refer to it occasionally.

Just curious about this. I was looking for some electrical info in the 57 Chrysler shop manual and I noticed that there are no electrical schematics at all. This is just strange, since my Desoto, Dodge and Plymouth shop manuals all have pretty comprehensive schematics. What do 300C and 300D restorers do in this case ?
