{Chrysler 300} Re: Unusual EL power pack— wire in tubing tied in knot

[John Grady <jkg@xxxxxxxxxxxxxxxxx>]

ps that resistor in the tubing is a joke always corroded inside black knotted tube and open .
Very low ohms . cut off at ends and open or pull out the resistor wire strand .
Measure overall length exactly — it was say 4” .( guess) 
Then zero your ohm meter carefully , on low ohms — measure 1” of the wire where good . expect 1 ohm or less . Then multiply by length it was . ( 4 ohms in this example .. not real value ) 
Then find on line a 5 watt wire wound resistor close to that number . 10 % error ok better slightly high than low . solder to end points 
You got this !

I replaced the cap (it had the usual Bendix 0.1 uF original cap) and it still didn’t work but I swapped in a different power supply and that one works fine, so EL lights are functional.  This one may have a bad power transistor (?) or something else.  Not sure if all these used any old TO-3 PNP transistor, or if the resistors are the same values in all these, etc… this one has two resistors (76 and 23 ohms) and some sort of thin resistance wire (on the order of 4 mega ohm) in a black plastic insulated sheath, which was brittle and broke while taking the pictures.  Different chassis configuration.  Seems like there is either a lot wrong with this or it’s just a different circuit with different value components than usual.
