Manny_7579 Posted June 29, 2020 Report Share Posted June 29, 2020 So I just have a quick question hopefully someone could help me out I drew up a diagram on how I’m thinking of wiring my electrical the little squares are fuses 300. just want to see if this is going to be the best way to go about it also everything is going to be under the hood since my truck has an extra battery option and all 0 gauge OFC wires alternator is a mechman 320 main battery is xs power D4800 and 2nd is xs power Xp3000 amps are Fosgate T2500bdcp and T600 and T400 thanks in advance Link to comment Share on other sites More sharing options...
1point21gigawatts Posted June 29, 2020 Report Share Posted June 29, 2020 Everything looks good except for connecting the battery’s negative posts. Ground the batteries to the chassis. Find the factory battery grounds and use them locations, just replace or add to with 0 gauge. Make sure the grounds are 18” or less or you voltage will suffer. My homeboy on here had a problem, his rear battery was reading way lower than his alternator and front battery and he shortened the 2 foot frame ground he had to less than a foot to a seat bolt on the chassis and now the rear battery reads the same charge as the rest of the circuit. Plus, his mids and highs amp had a 2 foot or so ground to the frame and it would cut off after a while, so he shortened that ground to a different seat bolt to the chassis and it solved his problem. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
1point21gigawatts Posted June 29, 2020 Report Share Posted June 29, 2020 Double up on positive battery to battery lead. And double up on battery grounds and double up on battery to alternator ground. And do a dual ground run from frame to engine block to step up a little on the upgrade. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
Manny_7579 Posted June 29, 2020 Author Report Share Posted June 29, 2020 @1point21gigawatts My only issue is that stupid ground sensor according to mechman all my grounds have to be ran threw there since it’s being controlled by the truck 05 and up GM have that Link to comment Share on other sites More sharing options...

1point21gigawatts Posted June 29, 2020 Report Share Posted June 29, 2020 That doesn’t apply for all the grounds. That’s just on the battery to alternator ground. Plus you still can ground your frame to the engine block as an extra upgrade. Have you ever heard of a big 4 upgrade? “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
Manny_7579 Posted June 29, 2020 Author Report Share Posted June 29, 2020 @1point21gigawatts Okay do you think the 2nd battery will charge good since the truck sensor won’t be reading the 2nd battery ground? and no I’ve never done a Big 4 upgrade Link to comment Share on other sites More sharing options...

If there is a ground that is connected to something that is connected to the main battery it will cause a funky charge. How he has it drawn in his sketch is exactly how I've had all mine. Ground the amps to the frame. Using the 1 (you can fit 2 in the sensor) ground to the extra battery ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...

Ground the amps to the frame. Using the 1 (you can fit 2 in the sensor) ground to the extra battery Ok, I understand the sensor thing. But the battery grounds can be grounded to the chassis, eliminating that need for another sensor(s) and he would only need a sensor in the negative battery post to alternator ground. But too long of grounds and the voltage will suffer. No matter how hard the ground is. Why ground the batteries to each other? Why not ground them to the factory locations on the chassis? And why use extra length to ground to the frame when he can use a shorter ground and ground hard to the chassis? Longer grounds always result in the voltage suffering. Always. Some less, some more. But always. So what not eliminate that future problem by shortening the grounds and grounding them to the chassis? “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
1point21gigawatts Posted June 29, 2020 Report Share Posted June 29, 2020 Steve Meade doesn’t connect the negative posts of his dual battery truck set ups. I haven’t seen many people do that on any type of battery set up. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
