Big 3 Help!

[Fear Of Theive 10+ year member]

i ran the first step of the first 3 ground to chassis,to the factory ground. but as i turned on the truck didn't notice a voltage gain or anything. i shut off my truck and 5 seconds later it sounded like a small rc plane was trying to take off in under the hood. so i was like ok. is this because of big 3 or what first time i noticed it?

The big 3 will not help you GAIN voltage... Research more... There is a search icon. Scroll up to the top of this page, about 1/2 way up and about 3/4 of the page to the right...

Also bumping every 5 min wont help either...

Yes, please read the big 3 tutorial first. it tells you exactly how to do it and what it does. As already said, you will not gain voltage, if you have voltage drops it will help stabilize the voltage.

Then undo the wire and see if it stops. The big 3 is not going to harm one thing on your car unless you did something wrong.
