Hey everyone, sorry this is first time here, so apologies if I'm not adhering to all of the rules.

But Bronco battery keeps giving me the deep sleep and is now dead, I just bought a trickle charger for the time being before having it serviced but I wanted to make sure I'm doing it correctly as I'm not the most car savvy. I bought the Noco Genius 1 and in the directions it states: For negative-grounded vehicle only, connect POSITIVE (RED) battery clamp or eyelet terminal connector from battery charger to POSITIVE (POS, P. +) ungrounded battery terminal. Connect NEGATIVE (BLACK) battery clamp or eyelet terminal connector to vehicle chassis or engine block away from battery. Connect to a heavy gauge metal part of the frame or engine block.

First off, is it a negative-grounded vehicle and on the picture below where would I need to attach the Negative battery clamp... IE where is the chassis/engine block away from the battery.

Thanks for all your help.

This was happening to me. Turns out I had a recall and a TSB that was like 4 hours of programming/module updates. They also gave me a new battery (after it was replaced 45 days prior). No problems since. It’s been about 60.

Also, is that a Bronco Sport?

I use a Battery Tender trickle charge. Connect the positive cable to the battery’s positive terminal. Then, connect the negative cable to any UNPAINTED nut nearby to ground. Finally, plug in your battery maintainer into an electrical outlet.To remove, simply reverse each step in reverse sequence.
