"Battery Tender" under the hood 2017 SS
Been searching for a diy under the hood install with the battery tender eyelets. One that I could leave attached and just plug into. This has been a bit of a challenge because the positive post is small and at first glance, it doesn't seem possible....however, I came up with this idea so maybe this may work for you too.
Please note: I am not a certified mechanic, the project below has worked for me, however your results may vary, therefore I take no responsibility for the outcome or your ability to perform this task. So...on with the project! 1)Below are the tools and procedures I used for this project. 2)The tender eyelet on the cord is to big to fit around the (+) post. So I cut a 1/4" piece out of the eyelet to reduce the size. 3)Using the needle nose pliers shape, reform and mold the eyelet to make it smaller. 4)Then use the pliers to pinch the two ends together to form the new eyelet, then test fit until the eyelet fits snug around the post. 5)Then hook up the tender power cord to the eyelet and route through the hood latch, down and out through the front grill. 6)(Optional) The (+) cap will not fully seat back on the bracket until you make an adjustment with the Dremel the cap will sit on top of the eyelet cord just fine if you choose not to go this route, however I prefer a clean look. 8)I used the cone grinding stone to form a cutout so the cap will seat back on the bracket around the post. 9)All clean and buttoned up. I've been using this setup now for 2 weeks trouble free. Good Luck! Last edited by 1hprush; 09-06-2017 at 11:41 AM. |

Interesting, and thanks for posting your process. You don't really indicate how you secure hot lead to the post beyond just putting the plastic cap back on. Also, what are you doing with the ground? Have you had any issues with running the cable through the hood latch area? Looks a little precarious to me.

None so far, except maybe if you forget to unplug it before moving you car. The only other was a personal preference, I wanted the (+) cap to fit back onto it's bracket, so I had to modify the cap, easy to do if you have a Dremel. However, make sure you unplug it if lightening and thunderstorms are in the area. Last edited by 1hprush; 09-04-2017 at 07:03 PM. |

May I suggest you put a flat washer and nut on the stud in case you get an intermittent connection.

Check for 110V Voltage when connected to 12V
FYI,
A battery tender/charger is only a type of transformer. After you connect the Tender to your Car's Battery take a 110V Volt Meter and check for voltage on the Edison Plug on the Tender/Charger. You might be surprised that its now converting 12V to AC(volts) by being back-fed. |

It seems that you are attaching the battery tender loom to the front of the car that is for jumping the car.
Is there any difference from attaching directly to the battery posts in which case you will need to figure out how to get access to the battery in the trunk. I can only see half of the battery and one terminal when inspecting through the side panel opening in the rear right trunk area. The Pinhead post went right over my head talking about converting 12V to AC. Care to explain that? Thanks I was going to try to hook up my battery tender loom this evening or the camaro charger as I am leaving the car sitting for 2 weeks starting tomorrow. |

The front charging posts get to the back battery, so it doesn't matter if only half the system is connected to it , the full charge is going to the battery. Perfectly acceptable to charge from the front.

My comment was more of a FYI safety note. A battery charger converts 110V AC to 12V DC via a transformer. Some Cheap/Chinese-made Battery Maintainers/Charges can produce AC conversely if/when connected to you car's battery, (12v In=AC Volts Out). If you leave this type of charger connected full time to the battery it can constantly produce AC(shock potential) and also run down your car's battery. Most high quality professional batt chargers have self protection circuits(and/or diodes) that prevent this, (Look for ones that a self disconnect circuit and/or have reverse polarity protection) Just disconnect the charger from the Car's battery when not in use and you'll be fine.

Connecting the tender to the post under the hood is a method I have used for years and use it on these vehicles and never had an issue. For me it just a simple plug and play feature. Jeep Grand Cherokee/Dodge Durango R/T/Dodge Viper/C6 Lingenfelter Corvette. |

Remove the plastic cover that surrounds that + post and you will see many powered, unused threaded studs available.
