Guest Truth80 Posted October 24, 2012 Share Posted October 24, 2012 1954 Plymouth Savoy. I can't get the dome light to turn off. Is there a switch somewhere I am missing? Link to comment Share on other sites More sharing options...
keiser31 Posted October 24, 2012 Share Posted October 24, 2012 Try turning the dash panel lights down and see if that works. Some MoPars have a "click" when you turn the light switch or dash panel light knob to the right. That turns the dome light on. Link to comment Share on other sites More sharing options...
Guest Truth80 Posted October 24, 2012 Share Posted October 24, 2012 I'll try that. it does stay on all the time. I'll try both directions. Link to comment Share on other sites More sharing options...
Joe Cocuzza Posted October 24, 2012 Share Posted October 24, 2012 There could be (not sure with later cars) a switch on the inside of either, or both, door pillars. It is a slide switch and is located about shoulder height when sitting in the car.. The other thing could be that the door jamb switch is not making contact when the doors are closing. May need to be cleaned, or ....... Link to comment Share on other sites More sharing options...
Guest Truth80 Posted October 24, 2012 Share Posted October 24, 2012 Ok Thanks. I will check to find a slide switch. Cant find the door jam switch. Let you know about the other.. Link to comment Share on other sites More sharing options...
Guest Posted October 25, 2012 Share Posted October 25, 2012 If all else fails you probably have a short between the lamp and the switch. Generally dome light switches both jamb and slide type are used to ground the circuit. Link to comment Share on other sites More sharing options...
Guest Truth80 Posted October 25, 2012 Share Posted October 25, 2012 I think someone removed the switch because there is no door jam switch and I can't find one anywhere else. Guess I'll have the trace the wireing and install a switch. Thanks for reply! Link to comment Share on other sites More sharing options...

Guest Commodore Posted October 25, 2012 Share Posted October 25, 2012 Well I cann't find a wiring diagram for 1954, but this site has one for a 1955. It shows a switch on the right hand door and another switch. Good Luck.MyMopar - Mopar Forums & Information - Mopar Wiring Diagrams 1955 to 1959 Link to comment Share on other sites More sharing options...

Guest Truth80 Posted October 25, 2012 Share Posted October 25, 2012 On the righthand passanger door! Isn't working but I found it! Never seen one only on passanger side before. Thisn is my first restoration and I'm not real swift at it yet. My first car as a teenager was a 54 Plymouth savoy. So I bought one 2 months ago and I am now working as a novice at it. This form has been a big big help. I still got things to ask tho!!:confused: Link to comment Share on other sites More sharing options...
Rusty_OToole Posted October 26, 2012 Share Posted October 26, 2012 What happens when you shut the doors? There is a switch in the door jamb of both front doors to turn on the light for safety and convenience when entering and exiting at night.You should be able to shut the light off by turning the headlight knob all the way to the left.

Guest Truth80 Posted October 26, 2012 Share Posted October 26, 2012 Nothing! Stays on all the time. I'll check the switch and wireing tomorrow. It only has switch on 1 side. Link to comment Share on other sites More sharing options...
Guest Truth80 Posted October 26, 2012 Share Posted October 26, 2012 Someone told me that when I cjange the oil I have to add zinc. They say modern oil doesn't have the same componets that the flathead 6 requires. Any truth to that? Link to comment Share on other sites More sharing options...
Rusty_OToole Posted October 26, 2012 Share Posted October 26, 2012 Don't think so. The cars that suffer from lack of zinc are OHV pushrod type engines like Detroit V8s from the sixties and seventies. Especially the high performance models with hot cams and stiff valve springs.Today's overhead cam engines don't need the zinc because their valve trains are so lightly loaded. Just like your "underhead cam" six lol. Seriously, your car's valve train is very simple and light with light valve springs. The lack of zinc shouldn't hurt it.If you are concerned you can use Shell Rotella 15W40 or diesel rated oil. They still have zinc . Link to comment Share on other sites More sharing options...
Guest Truth80 Posted October 26, 2012 Share Posted October 26, 2012 Ok, thanks Rusty. Thats good to know and helps me out... Link to comment Share on other sites More sharing options...
c49er Posted October 27, 2012 Share Posted October 27, 2012 Most all newer cars-2000 up use rollers on the cams so no need for Zinc although now timing chain failures are cropping up. A 1953 Plymouth hardly has any spring pressure but it wouldn't hurt if you cherish that P24 Plymouth.Bob Link to comment Share on other sites More sharing options...
Guest Truth80 Posted October 27, 2012 Share Posted October 27, 2012 yes, OK. I'll look into it more. Thanks Link to comment Share on other sites More sharing options...
Rusty_OToole Posted October 28, 2012 Share Posted October 28, 2012 They didn't start adding zinc until the advent of OHV V8s in the early 50s. Some of the first ones had a rash of cam and lifter failures. Then they added zinc to the oil and the manufacturers improved their materials and solved the problem. Your Plymouth is one of the "old school" designs before zinc. The zinc can't hurt but is not strictly necessary.I would be more concerned about upper cylinder and valve wear. The long stroke engines have more friction in that area. A shot of marvel mystery oil, redex, bardahl or your favorite upper cylinder lube can help, but again, not strictly necessary.

Rusty_OToole Posted October 28, 2012 Share Posted October 28, 2012 The wiring diagram shows power going to the bulb, controlled by 2 switches on the ground side. There should be a switch on the door post or on the light itself (you say this isn't there on your model) the other switch is on the door post.So, the problem seems to be a short or ground between the bulb and the switch. I suspect the wire has fallen off the back of the switch and hit the body or, the insulation has worn through on the wire at some point. Or, a defective switch.

Harold Posted October 28, 2012 Share Posted October 28, 2012 The door switch may be built into one of the screws that hold the upper door hinge to the A-pillar of the body. The center of the screw pops out when you open the door. This switch was first used on '52 Plymouths and continued for a few years.I also recommend joining the forum at p15-d24.com which is dedicated to flathead-era Chrysler products and has many knowledgeable members.www.P15-D24.com - Powered by vBulletin Link to comment Share on other sites More sharing options...

auburnseeker Posted October 29, 2012 Share Posted October 29, 2012 If the switches all seem fine you may want to check the wiring to make sure it isn't grounding anywhere. I had that problem in a 49 mercury I worked on this summer. Good luck. I just hope someone else wasn't in there before you. That can make things a whole lot more complicated.

Guest Truth80 Posted October 29, 2012 Share Posted October 29, 2012 I really think that is a major part of the problem. Someone else put a new radio in right under the dash near the door. So I don't know what they may have done. Soon as this weather is over I am going to get into it. Will keep all posted. Link to comment Share on other sites More sharing options...
Guest Truth80 Posted November 6, 2012 Share Posted November 6, 2012 thanks. did that today and will finish tomorrow. Link to comment Share on other sites More sharing options...
Guest Truth80 Posted November 7, 2012 Share Posted November 7, 2012 I FINALY GOT THE DOME LIGHT FIXEd. The switch in the front passanger door worked. There must have been a short some where in the line between the switch and the light. I finally just ran new wires from the switch to light and it works fine now. Thanks for all input!

Guest Truth80 Posted November 15, 2012 Share Posted November 15, 2012 AND! after I rewired it I found a second switch that I could not find before. For future, it is located behind the drivers seat up on the post coloum that diveds the back and front window! Link to comment Share on other sites More sharing options...
