{Chrysler 300} Re: Success (almost)

check 12 v on input to power supply , the orange wire , that it stays there with lights having gone off . — to separate the 12v car wiring from power pack / HV 
Did you change wring or  a mistake? the dash lights go on with headlight switch  — nothing to do with  key ? ? loose main wire at key ?does  incandescent 12 v in transmission or heater stay on ? 
run 12 from battery direct to orange  feed into ps leaving the white connected .. should light up 
Dimmer  resistor  on headlight switch is common offender on erratic dash lights . hard to fix  right too , you can short out that resistor so lights  stay full bright , which  in general is where you leave it anyway .
Separate a ? 12 v issue from pack or hv issue first . 
If hv , any gauge shorting  out kills all hv / gauges usually  without hurting power pack ,— vibration of key may be shorting some gauge radio tach etc . if that is case , disconnect white one at a time till you find  it  
Common offender is tiny wire in gauge to needle touches metal , one at a time will find which one 

hope this helps
there is no overvoltage shut down , that looks nice and  bright ! 
Anything from 190 -240 works , ac, higher end  is a little brighter 

Cap you put in is st least 630 dc right? less rating can break down
