Factory Radio Dims or Restarts When Traction Control Activates

[George B]

1. Today our roads are pretty clear so no more testing the TC activation but I do have more data.
2. I went out and key started the truck this morning. Seems to turn over a little faster.
   the voltage was just to the right of 14.
3. I had no issues on the way to work. I even remembered another time the radio restarted was when I actuated “up” for both rear windows at the same time. It didn’t glitch.
   
4. After work I remote started and ran it to almost the full ten minutes.
   
5. I noted the voltage when I keyed on was way over to the right near about 16 this is where I have the trouble.
   
6. Actuating both windows resulted in dimming of the display.
   
7. All four windows knocked it out.

Does this thing not charge when it’s remote started?
What is the difference here?
Maybe the battery is soft but it starts fine.
Can anyone point me to the ground for that circuit or for the TC?

Just my 2 cents. awhile back i installed 2 700 watt cooling fan motors and all was well until i slowed to tuen around on the first test drive of the fans. as i slowed to u turn the vehicle was at an idle with both fans on high and the factory bose radio went blank? Turns out i was pulling to much wattage at idle and bose is finicky to voltage drops, removed one 700 watt fan motor and reinstalled one of the 500 watt originals and fixed the issue. I also installed a 220 amp factory alternator and a 2 inch overdrive pulley to help with idle power draw on the system. How old is the battery? I would start there as cold weather kills battery's dead.

The battery is an unknown age. Gotta go.

Solved: I found what I believe to be the issue. The ground wire that is part of the negative cable assembly that runs to the frame under the right headlamp is damaged and corroded. I cleaned the frame connection with no improvement so I ran a temporary ground cable from the body ground by the brake booster down to the ground on the frame under the drivers door. I also replaced the battery due to unknown age or condition. This has corrected the issue as far as I can tell with several attempts to replicate the dimming issue while spinning the wheels in snow.

My permanent fix will be a replacement ground cable from the battery to the engine block and then using the original large ground cable from the block to the point under the front headlight. I will remove my temporary cable and save it for later use.

Mods,
Please add solved to the title.
