Shifter lamp

[topbanana73]

Hi all, found out my shifter lamp in socket only has one wire and is just hanging. Does the shifter lamp get grounded once installed in the receiving pocket under gear plate?
Thank you

the lead with the orange wire? I believe so, the "slap shifter" assembly is screwed to the frame and is grounded that way. The plastic console lifts off, leaving the shifter mechanism behind.

Shifter lamp, dash light, brake and tail ight, headlight and others are grounded through the chassis ground. Chassis just one big wire!

Thanks what I did do is temporary plug the lamp wire unattached to the acc fuse tab and no light. Tried 2 bulbs. Stumped…

Maybe bad socket?

That connector to body ground is marginal.
I installed an LED Bulb and it wouldn't work.
I ended up soldering a wire to the socket ground and running it to the mounting bolt for the shifter. Works great now.
In the future I'd replace the socket with something that has a dedicated ground wire.

Not that this is your problem. Some LED's are polarity sensitive.

Thanks Katfish, ill do that.

I am no expert(especially auto electric)however, your right, i installed an LED for the top left that shines on the control panel and it burned out as soon as i installed.
Thanks Challenger RTA

Do non-polarity bulbs exist?

Do non-polarity bulbs exist?

LED's, I would think so.

the majority of LED bulbs are configured for the center pin to be POS and the shell to be NEG. In most cases, this is not a problem, unless someone has altered the wiring configuration of their factory harness. Only once in my life, did I work on a car with Positive ground, a 1969 Jaguar XKE.

So the majority of LED bulbs are indeed polarity sensitive (unlike an incandescent bulb) but it's not going to be a problem in the most applications.

Thank you your very helpful
I’ll try it!

LED stands for Light Emitting Diode, by definition, a diode only conducts electrical current in one direction.
