Learning experience simulating a bad ground on a 2008 dodge charger

[stspringer]

Hello All,
I was checking out some youtube videos on electronic issues with cars and found this great site where there was a bad ground on the, left front, parking light/turn signal circuit on a 2008 dodge charger. I reproduced the circuit on a breadboard as a learning experience. I have it working, and I can break it too by removing the ground wire.

I am new to electronics, and I feel good about this learning experience. I have "momentary on" switches in place now but will add a turn signal relay for the turn signal circuit.

Please tell me what you think. Thanks

Yep, you can get all sorts of weird issues with bad earths on vehicles.
