Finally got cold here and it snowed. The FFE has been parked for the past 3 days. Was in garage working on the AWD winter beater and got a text message from the Focus. 12v battery low. Plug in now. I finished what I was doing (about 20 minutes).
Opened the doors to the FFE and all heck broke loose so to speak. Relay started clicking. Brake lights turned on, no response on dash. Plugged in the level 2 charge and nothing. Click. Click. Click. .....
Went down to the barn and got a battery charger. Popped open hood and hooked it up set for 2 amps. No change. Increased to 6 amps. No change. Click. Click. Click. Relay still raising heck. Brakes lights did turn off though. No response on dash.
Got a voltage meter. 8.5 volts on the 12v battery. What the heck????
Went back to barn and got the jump box. Hooked it up and the car went back to normal. Level 2 charger kicked in. Battery charger shut down after about 4-10 min saying battery was charged. Apparently, the level 2 charger was now charging the 12v battery based on the voltage at the battery.
OK... so I assume the 12v was drained due to features trying to keep the big battery warm? Do we need to keep these cars plugged up to the charger during the winter?
