Battery draining
« on: February 12, 2018, 11:21:05 pm »
Car has done this twice now. Sat for 2 days and battery dead.

Nothing has been added to the car, alternator chargers up to 14.4 volts, doesn't drop with lights, ac, radio on.

I havnt tried the parasitic drain test as I dont know how to get the car into sleep mode. I read online to arm the car alarm with doors closed (manually) and test fuses with meter not pulling fuses out as this can wake up some moduels, but how do I set alarm with the battery dosconnected?

Any help would be great.

Going to start with the bluetooth disconnected see how I get on.

keep the battery connected to test for current draw.

open the drivers door and pop the bonnet then engage the latches with by pushing a screwdriver or something through the latch, then alarm the can and let it sit for 15 min
it should go into sleep mode and then you can check the current draw and with the battery connected.

just remember to "open" the door and bonnet before you try to slam them closed!
