BAT jumping in log

Post by solosaniok » Fri Jul 19, 2019 1:54 pm

Hey guys.
I have an issue with the BATTERY log in smanager.
It jumps around ti much. I checked on my friends car and his log is much smoother an with less difference.
Because of that my ignition and AFR is jumping also.
It jumps between 14.1 to 13.3 V usually.
What could cause this behavior?

It could be an issue with corroded or loose wires, bad grounds, or a bad alternator.
