Nicole/Jager LED Instrument Pod Illumination Question

syoo8 · 11-07-2009, 01:44 PM

Do LEDs burn out?

I installed the Jager/Nicole LED kit into my instrument pod (86.5) and the right LED started flickering, then went out, followed by the left, followed by the center. Is there such a thing, or do I have a bad connection in there?

Connection would be my guess. Did you try fiddling with the dimmer wheel?

Just pulled the instrument pod and tested each LED by hand with a 12 volt power supply-- each of them are dead.

Did I get unlucky with a bad batch of LEDs, or is there something happening in my electrical system to burn out LEDs?

What voltage do you get at the sockets?..... Could be bad LEDs but rule everything out first.

I don't know what voltage at the sockets because i had to pull out the instrument pod to get at the LEDs. However, when I feed 12 volts through pin 16 and 17 (ground) I get 12 volts at the sockets, so there's nothing weird happening there.

Check voltage on the car side of the pod connector to be sure.... Sounds like they failed....Nicole/jäger are great at customer service shoot em a line or call, they will take care of you.

Dissected the LED, which had a 270 ohm resistor soldered in. (The resistor was hidden by white tape which I cut out.)

I don't know what the LED current is of the Jager illumination kit but most LEDs are 2 mA, 10 mA and 20 mA. If that is so, the resistor necessary would be between 500-5600 ohms.

In other words, if the LED current is between 2 and 20 mA, then the wrong resistor was installed into the kit, which resulted in the LEDs blowing out. I am going to the store right now to buy replacement LEDs and resistors to see if this solves the problem.

When did you purchase, and when did you install them?

PM or email me, if you got them through me.
