1.6 amp parasitic draw - 2020 Ford V-10

Thank you all. Excellent suggestions about things to check.

I assume the control module would draw less than 0.10 amp

Ran into a jammed CD on a radio that would kill the battery in a day or 2. The unit was trying to eject the CD but you couldn't hear it.

IF the 2020 Ford dash has the standard Headlamp switch with the roll wheel Dimmer----IF that wheel is rolled to the click position(normally turning on the overhead light, NOT installed on most Chassis), that engages a relay. Even with NO light connected it will cause a drain from that relay. Also some RV makers install a light to that switch, but that light is in front above the radiator and not easily seen if on unless at night. Doug

I have 2006 Winnibego Ford V10. I had a draw on my battery to the point it would be dead after a week camping. It turned out the alternator was bad and drawing down from the battery.
