I'm fighting with a 2017 580N-EP that is somehow back feeding power to the display when the key is off. The display unit backlighting and hour meter will power on about 5 seconds after the key is shut off and then it will intermittently shut off and repower itself about every 10 seconds. I have tried pulling power relays one at a time but none see to affect this issue. Any help would be greatly appreciated.
I ran into something like that. Try pulling neg battery terminal then check for voltage between positive and frame I've seen batteries bleed power thru the case
Sometimes, the alternator can do that. You can try removing the B+ wire from the alternator and see what happens.
I did disconnect to see if a vampiric load was present. But as of yet I have been unable to identify where it is originating. Only that it is powering the instrument cluster display.
I will disconnect the alternator and see if it resolves the issue.
Are there any codes when you look in the display ?
No current codes.
OK, Problem solved. Through trial and error, found that the menu on select button had an internal short. This is the button between the Parking Brake button and the Menu Scroll button. Because of the internal short it was causing the display to enter the key off hour check mode which allows a user the ability to check the hours without having a key. Thank you guys for the suggestions.
