So I have a fair amount of Electronics in my truck. pretty extensive stereo system (but thats powered off a Cap so it doesn't count) off road lights front and rear, a few other things, So i was driving home earlier headlights on. i pull up to a stop light with my blinker on and i glance down at my cluster and i could see my volt gauge jumping up and down along with my blinker. Blinker on gauge drops, blinker off it raises again. does anyone truck do this? i mean i can have my lights on and crank my stereo with no dimming or movement in the gauge. but the blinker makes it jump. Oh and i have just a regular battery in there, I'll switch to a red top when money permits.

it's caused by where the voltmeter is getting it's voltage.

so my gauge gets its power from where my blinker gets its power? i mean it doesnt matter i just thought it was interesting. shouldn't they all do it. i mean they all have the same wire harness

Mine usually does that when I have my LightForce's on.
