I have a radar detector that display voltage. I have noticed since I unplugged BMS at the negative post, the radar would never shut off and when I would come out in the morning battery voltage would be 11.9-12.3v, not a healthy charge.*
Last night I plugged BMS in and left the hood cracked. This morning radar was off and my voltage via multimeter was 12.67v.*
Anyone seen this before? Ive read numerous threads about disabling BMS on the gas engines and no problems. Something seems to be different with the diesels.
Just guessing but the BMS can shut off various components and systems if they remain active after the truck shuts down. Seems a radar detector would be minimal draw though. I think it is the same system as the other F150s.
