2002 Jeep Grand Cherokee Laredo 4 liter automatic

Okay guys I need some assistance,

I have no illumination in the automatic transmission / Transfer case at
night.

I original assumed that the bulbs had burned out but when I removed the
console I found not bulbs but an electro-lumiscent panel.

I was unable to borrow a voltmeter but I was able to get a 12v test light.
There is power going into a "black box" that is between the wiring harness
and the electro-lumiscent panel. The output side of the "black box" did not
illuminate the tester but I do not know what voltage would be on the output
side.

Is there a way to test this "black box" or the electro-lumiscent panel?

Thanks,
-billy

There's nothing listed: http://www.wjjeeps.com/lamps/lamps.htm
Maybe you're thinking of Japanese cars where their buyers are to stupid
to figure out where park is.

Now Bill, I am sure there are drivers of American cars that are too stupid
to figure out how to put their vehicle in park. I might even be one of
them.

Any ideas on how to test the "black box" or the lumiscent panel?

For sure, that's why the only vehicles over here with clutch interlocks are
US built :-)

In terms of us becoming more litigious ? Can't disagree with you sadly.
Or did you mean me forgetting to depress the clutch ? Nah, it took me 6
months to realise the interlock was there as I always depress it. Only found
out when my Dad complained it wouldn't start.

It's 60-120 volts at about 2-5kHz.

Sure, but you need test equipment. Your basic testlamp isn't going to cut it.

Hopefully we will never get quite as litigious as you , as here you have to
pay the other party's costs if you lose.

test it all you want because the parts are only availble with the shifter
