Re: [Chrysler300] 60-62 INSTRUMENT NEEDLES

[lettercars@xxxxxxx]

Hi Ken and All:
The details of the electroluminescent instruments are in the service  
manual---in the 1960 manual it is on page 61 of the Electrical Section.  An  
explanation of how the system works is there too.
 
Our Club member, Jeff Carter is the man in Oregon to have redo the  gauges.
 
I just had to change the non-functioning fuel gauge in my 300F.  The  
replacement gauge needle had little of the red paint left, so needed a  repaint.  A 
friend here in Tallahassee, Dave Patik who restores mopar  instrument panels 
among other things (Performance Car Graphics) just used a  little of the same 
paint he uses on any pointers.  All that is necessary is  that the color be 
similar to the original and that it not be applied so thick  that the 
electrluminescence is blocked.  The paint itself changes the  normal greenish color to 
red---nothing more as far as I know.  At night, my  fuel gauge needle looks just 
like the other gauges now.
 
Hope this helps a little
300ly, gil

Hi all  ;  Before I spend a lot of time experimenting with fluorescent 
paint  concoctions to apply to the instrument needles (that will male 
them glow  red/orange  when activated by the  instrument  high voltage  
supply) I thought someone out there has already come up with something  
that works.  The Model Master Fluorescent red (red /orange) colors  the 
needles ok (as well as other paints including translucent red/orange)  
but is not activated by the 150-200 vac - the bleached out gray needle  
color still shows through the fluorescent paint.   Has anyone  any 
information as to what the original dyed material coating ( I suspect  
the needles were dipped in a viscous conductive mixture is that the  
factor) is?   I plan to add various conductive  materials/solutions to 
the Model Master paint as first  attempt.   I'm aware of someone in 
Oregon that restores  instruments but having some 30 to 40  60-62 
instruments  (I only  need 6) I plan to replace the corroded, fine. wire 
to the needles and  recoat the needles -all myself - as I suspect I would 
be charged a fortune  if done by others.   Someday (after I get my car 
done) I hope to  be able to reassemble a number of functioning instrument  
clusters/speedo's, clock, etc.  I have and make them  available.

I vaguely remember seeing, many years ago,  some old  paper 
(advertisement?) describing, and showing details of the 60-62  instrument 
construction layer-by-layer,  the design of the  instruments and how they 
lit up.  If someone has this paper by chance  would appreciate letting me 
know  if the needle coating material is  identified!
