Hi, i found this site whilst looking for a solution to the following problem.
The purpose of the circuit is to indicate when electronic VIS motors on my car are turning on and off, so i know they are working correctly.
I have built the following circuit as per this diagram:

I have however changed the resistor (bottom left) for a 2k1 resistor as the designer recommended it.
The problem i am having is that I get 12vthrough the LED and diode, but 0v after the resistor which means the circuit is not complete.
How do i test the resistor to check i did not burn it out when i soldered it in, as i am no expert. I have a multimeter but no idea which setting i would need it on, or where to place the probes to check it.
If i can master this, I hope to be able to design more gadgets for the vehicle, but am rapidly losing faith in my ability!!
Any help is massively appreciated.
