Your alternator is going bad. There should be zero voltage fluctuation when an electrical load is introduced. I just replaced mine at Napa the other day. 80 bucks after core with a lifetime warranty. Well worth it imo.

I'm afraid you have to chase down the main issue first, start with the alternator.

Never mind lol my alt is not good. It had less than 9 volts coming off it when the car was on

Or maybe the voltage regulator?

You'll have to start pulling fuses to isolate the problem, basically disable system one by one to see which one is dragging the whole system down.

Could it be that I'm using 22-24 gauge wire for the information sending wire? Like it is losing voltage through it or something?
Nevermind... My stock gauges are also suffering from the problem, I don't think its anything that has to do with what I did to the car in terms of wiring. |

alright so I got it tested and they got it up to 70 amps and said it was fine even under load. Does that mean it's a ground?
A stock "70 amp" alternator will put out about 40 amps on a good day and will fail if you look at it funny. Pretty sure they're measured in Chinese amps, not real ones...:lol: Also, how to use a relay is literally a google search away. This is a good resource for beginners to bookmark, chick full of how-tos and such that cover all of the basics to handle wiring matters correctly: https://www.the12volt.com/ Anyway, read up on what I've written, and on the12volt, and you'll be on your way to straightening out this mess. |

I apologize in advance if I come across as rude, but this thread was painful to watch and read through when the solution has been in the Second Generation FAQ since before I joined 15 years ago. My post in your other thread referenced the article written by Aaron Cake that spells out exactly what is going on (Ohm's Law). I just went into detail about how it alters sensor readings and affects sensitive circuits.
