Electrical grounding problem located
Having read about a few others on here lately who have had some battery issues, I am passing along something I found tonight on my truck.
At times I have experienced a weak battery and the sight gauge on my battery often shows red. My trucks battery will drop down to ~9 volts when it cranks and then back up to 13+ volts after it is running.
I was looking to upgrade my "Big Three" this evening and happened to run across a grounding problem on my truck. What I found was one of the ground wires from the fender to the wiring harness was not tight against the fender. The bolt was very tight, but I could move the cable in and out on the bolt. Below is a picture of the location I am talking about on the passenger side fender. The cable in question is the one on the right and the picture is from after I installed an additional ground cable to the location as a part of my upgrade.
I am hoping this will make a difference going forward as I clearly was not making a solid ground on this wire to the body.

Very interesting! I wonder if this has anything to do with the pulsing rear lights I posted about a while ago...

Where did you run that extra ground wire to? And what gauge is it?
Thanks!

I was under the hood last night running power for a 2m radio when I noticed the grounds appear to attached to the truck over paint so to speak....maybe I'm wrong but wouldn't it be better to have them attached to bare metal rather than painted metal ??
I'm thinking a little Dremel work would clean them up nicely..
