[QUOTE="Mystic Knight, post: 3273584, member: 574367"] Here's a little quiz concerning something I just noticed while wiring up my truck. I have a '91 S15 Jimmy that's been heavily customized. I'm slowly getting things back together. As I've been wiring up the custom led lighting I've noticed something that left me scratching my head. Nothing really wrong. Just had me curious why it's doing this... If I ground my multimeter to the body and put the + to the turn signal hot I get a constant 12v. Not alternating as expected. If I ground my test light to the same ground and put the tip to the turn signal hot the test light blinks. I then went one step farther and wired the test light up again then touched the multimeter to the test light leads. Then I could see the voltage alternating between 11 and 4v. My question is this: What makes the test light blink when the multimeter reads a constant 12v? Does the multimeter carry no load? I've installed an "electronic no-load flasher" which I assumed would flash regardless of the load. Any ideas anyone? This is just a curiosity thing. [/QUOTE]
