Where to start looking for wiring problem
I've got a floating wiring problem, and I'm thinking its tied to the left turn signal somehow. At first it was just an occasional alternator whine in my normally distortion free stereo system, and it did it even with the headunit turned off. A few days ago my left turn signal started blinking really fast like it does when a bulb is blown. I started it up today to see which bulb was blown and the signal blinked at the regular rate, no bulbs are out, and the stereo is back to quiet. Also, when its doing it you can hear the whine from the AC/Heat fan as well.
I figure something is grounding out, which is what's causing the whine through my amps, which are grounded directly to the frame, and also causing the left turn to act like its out.
The original owner did have it wired for a plow, so I'm wondering if its something in that or if some OEM wire is rubbing.

I'll check. I already buy in an extra cab to frame strap when I installed the stereo.

Run a ground DIRECTLY to the battery ground! I think that'll take care of your problem.
Oh yeah, run at least the same size wire you used for you hot lead.

From the amps? How would a bad ground for the amps affect the turn signals? The turn signals blink fast like that when they detect extra resistance and assume its a broken bulb filament, right? A bad ground for the amps wouldn't cause that, and the amps aren't a new install. They've been like that for the better part of two years and didn't have the noise before.

Of course, I can't get the problem to repeat now when I have time to deal with it. I checked the ground at both batteries with a volt meter and they read the same from the pos direct to ground as they did pos to neg terminals, so the ground on the batteries should be good. Cab to frame ground is good.
Is there a seperate engine ground beside the one at the front passenger side that goes to the passenger side battery?
