Had the exact same problem after I bought my '12 M56S back in March of this year. My commute to work is exactly 8.1 miles and apparently, the alternator doesn't engage until after 8 miles. After the first couple a days driving to work and straight home, the battery drain finally caused my engine not to start. I had my battery load tested outside of the car and the charging system checked with both showing no issues.ibc wrote: ↑Fri Oct 30, 2020 1:43 pmTake a look at this thread:

Are you taking many short trips these days? The ECM intentionally disables the alternator from charging your battery during short trips. It bit me. No more dead battery since I bypassed this stock Infiniti "feature".
You'll have to remove the battery access cover then remove the frame that the battery cover sits on. Remove the right side cowl and remove the battery if you haven't done so already.
Got it. Thanks! I'll do this tomorrow.C6Joe1957 wrote: ↑Sat Oct 31, 2020 3:33 pmYou'll have to remove the battery access cover then remove the frame that the battery cover sits on. Remove the right side cowl and remove the battery if you haven't done so already.
EdBwoy's video on getting to the IPDM. https://www.youtube.com/watch?v=aoW_pp7XRiE
The IPDM is the box that sits to the left of the battery looking from the front of the car. Slide it out, remove the IPDM cover and you'll see the CAMBUS connector that has the yellow wire #76.
You will need a skinny, flat tool or a terminal removal key tool if you have one to slide into the yellow wires terminal to release the yellow wire's connector.

Wish now that I had taken photos but to the best of my memory, that's how I removed it. After removing the wire connector, I place a skinny 1-inch length of heat shrink to shield it from grounding on anything and tucked it away.
Thanks! I saw comments about a yellow wire and got really confused. I'll try this one this weekend.Ilya wrote: ↑Mon Nov 02, 2020 9:21 pmNot sure why your wire is different but here are some pics:

If ever there was consensus, I would say it is "Yes, do the mod."DoN_BLaZe34 wrote: ↑Wed Nov 04, 2020 11:43 amSo gents what's the consensus on this mod? Is it worth doing? Do you guys feel like it helped? It may be in my head, but I feel like I've seen/read mixed reviews
