Re: IML: steady drop in EL brightness?

[randalpark@xxxxxxx]

I think that I agree that you are describing two separate problems. The 
gradual dimming of the dash lights is usually caused by a failing power 
pack. The pulsation is usually caused by high resistance in the 
charging circuit.

Subject: IML: steady drop in EL brightness?

Just now starting to drive and enjoy my 63 custom but noticing a 
dimming of the panel lights as I drove across town saturday night to a 
car show.  The dimmer does work; the overall brightness range is just 
depressed.  There is also the annoying pulsation of the regulated 
voltage on the entire grid; my DVM at the battery rhythmically 
oscillates between 14.2 and 15.7.  I speculate these are unrelated 
separate problems but maybe not. Another theory I have sees the power 
pack heating up over time and dropping output voltage.    Has anyone 
noticed this symptom?    My next test will be to put the DVM on the EL 
output and monitor it over a long haul. 
I must say I am shocked how few people notice the car as I go 
about Tucson Arizona.  No looks, no whistles, no horns, nothing.  It's 
not like there are hundreds of them out there.  I expected more than 
this though.  Maybe the desert heat toasts our brains and we have 
become oblivious.  --Tom
