Just as the title says, did the big three upgrade last night and now when I start my car it immediately says "tcs off" which is great...because i turn it off regardless when i start the car. Did I blow a fuse?

Thanks

what the hell is the big3?

It means he upgraded the wire from his batt to the alternator, block to chassis ground, and batt to chassis ground. And i'm not sure, maybe you might have knocked a wire loose. I'd just start where you wired up and see if you can find anything.

Deff just trace ur steps and find the loose wire

when I did mine on my mustang it was at the same time I was putting my new alternator in so I did my power wire new alternator car fired right up so I went to do my grounds. And I put one of them with the factory grounds and didnt realize one of the grounds fell out from under the screw and was danglin there. Spent 5 hours trying to figure out why the car would only run for a second. Yeah found that pcm ground eventually

would a big 3 upgrade help with a factory alternator ?

It would help with your factory equipment because it helps make whats already there be more efficient. Kind of like a higher flow exaust system on your stock car would help your power output because of better flow. Hopefully that makes sense. I'm not saying that it will increase the output of your electrical system/alternator but it can make it charge back up more easily with larger gauge wire because there is less resistance thus improving it's performance in that regard. I definetely saw improvement when I did mine with 2awg wire. So there is a performance increase in that respect.

Guys i have 2 question ill be more than happy if u could answer.

Q, I went ahead and bought a 70mm2 (welding wire). it`s a super flexable cable. do u guys suggest i USE it or NOT for my upgrade ?

i took a pic.


another Q, a 70mm2 wire is equal to what gauge wire ? (in other words what is the diameter (in mm) of a 1/0 gauge wire) ?


thanks

^ heard NOT to use welding cable. What I understood about it is it is made up of many tiny copper wires and will brweak over time, so it is not good to use it.

pentavolvo

use welding cable for stereo instals all the time, so no reason not to use it for this

idk what gauge it is but it looks to be maybe4?
