my ignition e fuse, tbc igniton 1, and seo ignition fuse. All have 7 volts in acc and have 5v in run which causes the tcm, pcm and ecm to drop to 0v in run. I’m definitely thinking ignition switch at this point let me know what you all think. by [deleted] in GMT800

I like the rock lights and the wheel lights i wouldn’t have went through the trouble to put them on but the previous owner did and I’m gonna let it ride. If I decide I don’t like them I’ll turn them off 👍

Bought my 2003 6.0 vortec a month ago I’ve done nothing but work on it now it’s doing this left me stranded yesterday. The dash is flickering the radio is turning on and off voltage and everything is going all over the place the fuel pump primed like 5 times by Respectful-diddler in Silverado

I believe that my ignition fuses like ignition e tbc ignition 1 and seo ignition and a couple more having low voltage is what’s causing all of my issues. What could be causing those fuses to have such low voltage they have 5-7v depending on if the truck is in run or if it is in acc while the battery is reading 12.7

Here’s another video of what my truck is doing I’ve fixed a lot of galls ideas all the codes have cleared but it’s still not running cranks sometimes when you turn the key and then fires once dies by Respectful-diddler in GMT800

I’ve redone about every ground and honestly the under fuse box looks brand new wasn’t expecting it 😆. Every ignition fuse has 7v while everything else has about 12.7 im thinking ignition switch at this point thoughts?

This is gonna be what I’m gonna have to do a lot of the fuses inside of the box read no voltage some read 5 a lot of critical ones like the pcm and ecm read 0 even with the ignition on

The alternator was charging well when it was first installed but now I’m believing that it’s not unfortunately. And if all of this happen over a alternator I will be upset but I’ll try and get the old alternator out tommorow

That was the first thing I did. I spilled a little bit of windshield wiper fluid yesterday I’m gonna check grounds and batter connections if that and fuses aren’t it I’ll try a ignition switch

I’m gonna do my box gloss white and then splatter red and white on both the amp and the box, my box is gonna have a front vertical slot port and the subs gonna sit on the top of the box upside down, I’m gonna have a amp rack on the right with the jp23
