Big 3 kit for Diesel

Hey guys, new member. I have a 2014 Diesel Cruze. I searched for quite some time in regards to a "Big 3 Kit" for the diesel. I can find lots of information for the gas jobs but nothing for the diesels? Can anyone shed some light on this topic?

Thanks

Welcome to the forum! I have been on this forum for over 2 1/2 years and I've never heard of a "Big 3 Kit". Can you enlighten me please?

Thanks! I actually just bought the car, I was putting too many kms on my truck commuting to work.
It is putting larger ground and power cables in. Alt to positive battery terminal, engine to frame ground and battery negative to chassis ground. Lots of car audio guys do this before they put stereos in. The gas cruze guys are doing it to reduce headlight dimming when the alt kicks in, helps take strain off of the charging system, etc

Here is a link, the member selling the kits hasn't been active for 2 years. The topic still gets talked about though.
Oops wont let me post a link until 3 posts
Seems like a good idea if you are going to be putting a biggie stereo and amps in. Otherwise, the diesel model already has a slightly bigger alternator and battery than the gas Cruze.

Do you know if this would help reduce alternator noise? My system sounds fine until I release the hand brake and the headlights come on, then there is a buzzing noise.

I have a 1600 watt multi-channel amp running two 6x9s on channels 1&2 and two 12" dual subs which are bridged for a single 4 ohm impedance on channels 3&4.

Is that all through the stock deck?

Alternator noise is generally because RCA cables or speaker wire was run next to power wires and is picking up noise that way.

Yeah, that is exactly what I did. I was really hoping it wasn't that. In hind sight, I probably should have used a shielded power cable instead of 0 gauge arc welding cable.

Still think It's weird that I only hear it when the lights are on.

Yep! Generally you want to run RCA cables at least 18" away from power cables. Run them on the opposite side from the power. Check your grounds too. You need clean grounds for your amps.

I have double checked the grounds to the chassis but I fear there may be some resistance between the amp in the trunk and the battery under the hood. It was much easier in my cobalt when the battery was in the trunk.
I do know there was an upgraded negative battery cable for the diesel released under a TSB. Otherwise, I think the diesel's power output should be able to handle a stereo. It might only be a bit of a strain on a cold start with aux heater, glow plugs, headlights, heated seats and fan active.

How do we get this upgraded negative battery cable?? Do we have to ask dealer at service or complain??

it should have been done to a 2015

#14311: Special Coverage Adjustment - Negative Battery Cable Loose - (Dec 3, 2014)
Subject:14311 — Special Coverage Adjustment – Negative Battery Cable Loose
Models:2011-2015 Chevrolet Cruze
[HR][/HR]ConditionOn certain 2011–2015 model year Chevrolet Cruze vehicles, the negative battery cable terminal clamp may have an insufficient crimp at the battery negative terminal. Over time, the internal resistance increases and vehicle electrical systems do not receive adequate power.
With this condition, the following effects are possible: the Radio/HVAC Display may turn off and on; the Antilock Brake System, Service Traction System, Service Stabilitrac and Steering vehicle messages may come on and off; the turn signal sound may not be heard; “Battery Saver Active” and “Service Steering” may display in the Driver Information Center (DIC); and the interior and exterior lighting may flicker. Power steering assist may also be lost, and greater effort may be needed to turn the steering wheel at low speeds or while the vehicle is stopped.
Special Coverage AdjustmentThis special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.
Dealers will replace the battery negative cable, which will now require a bolt to fasten the small regulated voltage cable. The repairs will be made at no charge to the customer.
For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after December 4, 2014 are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to December 4, 2014 must be submitted to the Service Contract provider.
Vehicles InvolvedAll involved vehicles are identified by Vehicle Identification Number on the Applicable Warranties section in GM Global Warranty Management system. Dealership service personnel should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.

My MY 2015 build was early Dec 2014, so I am wondering if they got to this??
Tell them your battery saver light was on and mention the TSB. That should be all they need. That's what they put on my paperwork when I had it done.

theyre not allowed to sell a vehicle with open recall, correct?

the wiring would be spec'd to meet the needs of the stock cars usage.

add 200w of lighting, 1000w of stereo, etc i would think things would be taxed

"Supposed to" is one thing, reality is another. They sold it to me with the sunroof recall open :( I literally got notified by OnStar before the dealer caught it.
