Thanks guys and thanks for frankzlin79 for the reach out!
I have changed from using fuse 125 to 145. Can confirm working and charging only when ignition on - and more importantly, stops charging within seconds of turning ignition off! Pictures using fuse 145 with the correct orientation. Great work guys. I have amended my write up if anyone interested! Thanks again! https://f80.bimmerpost.com/forums/sh....php?t=1556755 Cheers Dave Last edited by im_dave; 12-30-2018 at 10:36 PM.. |

I identified the 12V constant fuses in a thread I posted here: https://f80.bimmerpost.com/forums/sh....php?t=1568109

I could not tell you which constant 12V fuse location is better (or more frequently used) as none of the aftermarket electronics I plan to install requires a constant 12V source, only a switched 12V source. Although, fuse locations 109 & 112, which have 12V constant power, do not have fuses installed in those locations (at least on my car). This means there should be no OEM electrical components connected to those fuse locations (as they are not getting power). If I were to tap into a constant 12V power location, I would start with one of those locations, either using the OEM way (which I documented in my post and my preferred method) or via the add-a-fuse method from the top.

First, I would not recommend using parking mode of your dash cam with your main car battery. While it is not guaranteed, there have been several posts where people have had issues with battery drain problems going that route. And we all know the battery in this car is not cheap even though the LiPo battery is pretty robust.
So, assuming you are not going to use parking mode, then I would recommend you use one of the switched fused locations that turns off immediately with the ignition.

Why the concern over the car powering the B-124 when the engine is running? When the car is running, the alternator is already providing power to the car's electrical/electronic systems. There should be more than enough power "surplus" to power the B-124 while it charges (and several other aftermarket electronic devices like cell phone chargers, etc) ......

As well, I have the car on a battery tender, so even less of a reason to be concerned. Thanks for the chat, jmciver! Appreciate the advice and clarification. |
