Bcole7 Posted May 16, 2021 Share Posted May 16, 2021 Hi everyone, I have a 2020 transit. I bought a Sirius satellite radio and I’m looking to keep the radio powered ON When the vehicle is turned off. There’s not much info on which fuses are hot when the vehicle is off. I was going to get one of those 20a 12v add a circuit fuse tap piggy back. Based on the diagram of the fuse box located under the steering wheel would I be able to tap into one of those? If not I’m sure I could tap into the horn fuse, but that’s in the engine compartment and would be more of a hassle. Thanks in advance.

jrm223 Posted May 17, 2021 Share Posted May 17, 2021 Unless Ford has changed something with the more recent ones, the factory 12V plug should stay hot at all times, unless something is drawing the battery voltage down too low & then the BCM turns off the 12V power port. My 2015 TC 12V is always on, I have even found my Sirius add-on radio turned on after not driving for a couple days, accidentally left on after my last drive.

Bcole7 Posted May 17, 2021 Author Share Posted May 17, 2021 Thanks for the reply. When I shut the vehicle off that outlet stays on for 15 mins or so and then powers off. So I’m guessing this is a feature in the newer models. I doubt it’s drawing that much power in that amount of time to shut it down. I had a dodge before this and like you I would come out Monday morning and realize I left my unit on. Never had a problem with the battery. jrm223 1 Quote Link to comment Share on other sites More sharing options...
DonShockley Posted May 17, 2021 Share Posted May 17, 2021 I did a test on my 2020 several months ago to see how long the outlet stayed powered after shutting off the ignition. Checked every 15 minutes or so and it shut off right around the 2 hour mark. Quote Link to comment Share on other sites More sharing options...
phollenback Posted May 19, 2021 Share Posted May 19, 2021 I have a 2018 and the power outlets seem to stay on indefinitely (days at least). I've never run anything down long enough to see if there's an automatic cutout. Quote Link to comment Share on other sites More sharing options...
jrm223 Posted May 20, 2021 Share Posted May 20, 2021 I bet it's a configurable option in the BCM, accessible via Forscan with an OBDII adapter. I've never looked for it, though, since mine does stay on all the time already. Quote Link to comment Share on other sites More sharing options...
