A little confused

[ncrc5315]

While I admit, that is not that hard too do, here is the situation. I'm working on a Stewart Hobbies Baldwin VO-1000, this model has a circuit board with an eight pin plug. On each end of the board, there are two copper tabs that extend off each end of the circuit board. The LED legs are bent in such a way, to contact the tabs. I assumed there was dropping resistor on the circuit board for the LED. However, when I check the voltage on the two tabs, there is ~14.0 VDC. I have the cab re-installed, and the rear light works just fine, and it also is showing ~14.0 VDC. What am I missing?

Are you measuring the tabs with or without the LED connected ?

Mark.

Both ways. That was my first thought, unregulated power supply, but when I applied the LED, same 14VDC.

Checked again, made sure there was good contact, and now I get 2.0 VDC. Guess I need to stop doing this late at night.
