Battery grounding question
So, I'm under the truck removing the front bumper in preparation for installing my new fog lights, and I see a black wire with what looks like a grounding "circle" on the end of it just dangling aimlessly. So I follow it to see where it's coming from.
On the driver's side battery, there's three black grounding wires coming off the negative terminal: one thick, heavy gauge wire that grounds on the bottom of the engine block, one thin gauge wire that grounds right on the body in front of the battery, and then a slightly thicker wire that is my mystery wire. I'm gonna say it should be a frame ground, but I figured if someone could go out and look at theirs, that would be a safer bet. So anyone know where this wire goes? I'm guessing the previous owner or my dealer disconnected it from it's grounding location for some reason and never reconnected it.
TIA.

Mine too. I think you have an engine ground wire, a frame ground wire, and a body ground wire. My guess is its the frame ground.

It's on the side of the frame, visible just in front of the driver's side wheel. It's on the exterior of the frame.

Cool, thanks. At least that's one thing I should be able to fix. Now if I can just get it running again after I changed the fuel filter! But that's another thread...

Youll never have a problem on filter changes again.

Go to auto zone and get a fuel pressure test gauge. It will say not for diesel vehicles. That is because of the fuel pressure on the high side of the pump, but we dont care because all I use it for is low side. Connect the gauge to the schrader on the VP where the line comes in from the filter. Bump the starter and depress the bleed on the test gauge until you have a solid stream of fuel out of the line. Itll fire right up. You can use the gauge at this time to check the pressure to the VP from the lift pump.
Youll never have a problem on filter changes again.

So now, plan B.

That should be the inlet for the IP. If you have no pressure there, you need to check the filter and the housing etc to make sure you do not have a blockage.
