Good explanations. Thank you.

I'm really confused, please sir help me! When an ECU activates/commands a component (like an injector) voltage GOES DOWN and remains down when activated. But when a light is activated voltage IS UP! That makes me think that that light is off. Greetings from Argentina, I like your videos!!
