The link to Amazon below is for the monitor I put on our Maverick's FLA battery under the back seat. Can pull it up on bluetooth when driving or in the garage. It gives an accurate state of charge. This confirms that Ford has a problem with recharging the Maverick and a problem with rapid loss of charge due to fantom current drainage. They really need to solve this.
What voltage are you seeing when your truck is in the ready mode?
Drove it across town today and after that round trip it is only at 86% SOC and 12.55V. By morning it will be in the 70% range and 11.6V or there about.
Best attempt at a short-version update:
Power port should be on for 75 min max.
It's been over two years since I set my delay timer. (Might have been the courtesy light timer and not this timer even). There were several selections 0, 15, ....75, 90 minutes. That is the countdown to OFF. The tricky tricky with selecting 0 is there is no countdown time and therefore selecting 0 will leave the circuit on until Battery saver turns it off. It may be possible that if someone using forscan sets the seconds to zero on the power supply circuit it will stay on. Seems like I read or someone posted that the time should be set to at least five seconds to allow the computer to have time to have the timer work a few seconds during key off procedure. Just a thought.
The auto lamp(courtesy light) delay is surely the one I set. If you need a longer time for the auto lamp delay you can set it to 15 minutes or whatever and when you get to where you do not need the light double press of the fob lock will immediately shut the delay off. (This will also darken the dash, radio, dome lights, etc if they are still on). It has no affect on the dash and bed powerpoints. There must something else on that circuit which the truck needs to have on to monitor or control. I am going to guess there must be a "weak" ground or one of several which may interfere with proper detection of a relay. But beyond my pay grade. There was one of the updates on my truck performed in my driveway which required 13v fed on the jump pins during the update to allow the proper testing of which items were installed or operating properly. I suspect to maybe calibrate something. ???
The power points turn off based on the rear PowerPoint timeout setting, not based on whether there is current draw. The current draw of the LEDs for the illuminated ports is less than 0.005A, so it's negligible compared to the power used by the truck in standby mode.
The hybrid high voltage battery has nothing at all to do with the power points. They are run off of the 12v battery under the back seat.
I read that as a description of which truck version - since the hybrid has a smaller 12V battery than the EB has. And prior to 25MY, FLA not AGM. Until we all get the next replacement under warranty anyway.
The PowerPoints turn off based on the timeout setting OR by the battery save voltage being reached. The power point voltage reading at my dash cigarette style is as much as 0.2v less than what it is at the battery. Where is the battery save reading taken? One would assume at the positive post with body ground as close as possible prior to any line/usage loss of the many items connected to to bus using their own body ground.
