Miscellaneous Electrical Issues

Recently my truck started having these strange electrical issues, and I am not sure what the cause might be, as symptoms are intermittent.

These are the issues I have had over the past 3 weeks in order:

1. Car Stereo, dash camera, and radar detector, keep losing power for .5-1.5 Seconds every 1-2 minutes for that drive home.

(I unplug and plug the 12V splitter back in, once home)
(No issues for a few days)

2. Every internal light on the truck starts flickering rapidly, almost so quickly you can't notice it, all while the Stereo, etc.. are turning off randomly.

(I look at the battery and see mild corrosion on the terminals, so I wipe it with a rag)
(No issues for 1 week)

3. I start noticing my headlights are dimmer than normal and my starter sounds weak when starting the truck, this goes on for a week, intermittently.

4. Throughout the week stereo, etc will power off and back on intermittently, the headlights run dimmer constantly.

5. While driving, I flick my headlights on and the whole truck shuts off for .75 Seconds, then comes back with no issue, albeit the headlights were still dim.

What do you think the issue might be here?

I am leaning towards the battery terminals corrosion being the problem. I am going to clean those today.

However it also seems like, the truck is running out of electrical Amperage, like there is a short, or the alternator is not producing enough current.

A lot of my driving is at night on rural roads, so the last thing I need is my headlights shutting off when I am going 60 down a rural highway at night.

 

Start with removing the terminals on the battery and cleaning them really well. I like to use baking soda and water. Get some of those green and red felt battery terminal protectors. I swear by them. Coat the terminals in some grease of your choice or the little packet of battery terminal protectant grease. Put it all back together and see what happens.

 

If none of that works check any other connection between the battery the alternator and grounds. Have the battery and alternator tested. It seems that our trucks really like a fully charged battery. Anything less causes issues.

 

I had the same issue, realized I broke my terminal connection. Look closely. Good luck

 

I appreciate all of the replies. I am going to clean the battery terminals, and grease them today after work. I might also check out the grounds to make sure they are tight and/or not corroded.

The battery is only a year old, it is an Everstart Maxx, the voltage consistently sits at the same nominal rating now. However when this issue first started, the voltage gauge was bouncing back and forth at about a 40° range between the nominal natch and the low notch.

 

Well, I cleaned the battery terminals and clamps with baking soda and a wire brush. The truck did its normal routine after the battery is unplugged... First time starting it always dies, Second time it runs fine.

No issues on the way to work today, so we will see.

 

2014 Platinum having save issue. No power lose , dash and radio Losing power.
May happen 3 or 4 times on 30 min drive .

Any update? Tia

 

Sounds like a ground. Did you try wiggling the positive and ground cables on the battery ? Corroded battery cable or a bad battery terminal ? Loose ground connection on the truck somewhere ?

These are what I’d be looking at first.

 

I strongly think you are starting to have dead cells or short in your battery. Whatever you do do not take the battery cables off the battery while the truck is running. You will regret it. Take it to a place like AutoZone and have them test the battery and test the alternator.
Also check all ground wires, On the body and frame.

 

This issue did go away for me. I am not sure what I did to resolve the issue. Most likely, it was the battery terminals were loose and corroded.
