I been having an ongoing issue last few months
Bought the car then starting installing accessories-
-Double Din Stereo
-Roof Top Screen
-EGT Guage
-Heads up display via OBD2
-Obd2 Dongle via OBD2
all accessories are using accessory power so definitely do not come on when key is removed!
Now I was having a daily battery drain. Even with brand new battery.
I noticed the Obd2 dongle had a light on even when key was removed.
So disconnected that and its been good.
Today it drained again but I didnt drive all weekend. Got in car to go to work.
So jump started and away I went
Tested battery is good after a drive
12.9 volts
Engine on at 14.08 volts so alternator is working.
now...
Did a parasitic drain test.
With heads up display OBD2 plugged in. I get a fluctuating 2 milliamps to 50 milliamp drain.
Without it. I get only a 2 milliamp drain.
is a fluctuating 50 milli amp enough to drain a battery if a drive is not long enough over the week?
