Mechman 370a installed and Big 3-Highlights and Interior dimming/voltage drop badly

Your stock ground should go from battery to the bottom of thr engine block. That's how my silverado is. Are you talking about the ground you added?

[Keagan-Z06]

I'm talking about the ground that goes through the battery sensor. If they both can't fit in the sensor hole then where do each go?

[ToNasty]

Oh ya. They are both small if stock. One goes to the e gone block and one goes to the frame under the left headlight

[Keagan-Z06]

Im not understanding this or maybe we missing each other. If I were to do the big 3, the wire that currently goes through the sensor, where would I put that if the new one from the big 3 needs to go through the sensor so as to not cause problems?

[ToNasty]

Take the stock one out if you want to keep a single alt.

But remember, if you have batteries in the rear of the vehicle you can't ground them too the frame because there's no sensor. You can squeeze 1/0 through it along with the stock ground though. It's just very tight

[Keagan-Z06]

Ahhh! Much better, thanks! I assume you are not very fond of the Big 3 upgrade on your truck?

[ToNasty]

I,don't have it anymore. I'm switching to multiple alts so I don't have to worry about it
