Every time I open the hood on my 2025 Bronco Sport,
There is a humming noise in the engine compartment.
I have not started the engine.
It eventually goes away.
Does anyone have the same problem or know what the hum is ?
Thanks for the good information.
Good to see I’m not the only one with what I call a big problem.
I have a 5 amp trickle charger and I installed a quick connect cable.
I just charged the battery today.
It took 6 hours.
I often don’t drive my 2025 Sport for over a week.
It then goes into Deep Sleep Mode.
What are the pros and cons of using a trickle charger versus driving it so it uses the alternate to charge the battery ?
