Won't run without battery connected...

[jfoj]

With any modern vehicle it is hard to really verify things if the battery is not fully charged.

I would clearly question the alternator, but with a battery at 11.7 Volts all bets are off. With the IBS and other things in this vehicle, you cannot always assume things are as you think with a low battery.

I KNOW for a fact that the E70 has a very hard time notifying the driver there is a charging system problem. I have had my E70 about 3 times not charge at all and there were no warnings. I run an UltraGauge an have Voltage and temperature threshold alarms which I have seen the vehicle not charge at all for miles. I have pulled over and restarted the engine and the charging has come back to normal. I am question the regulator in my alternator, will probably replace it proactively here shortly.

I do not know why anyone that frequents forums does not own a decent battery charger at a minimum.

Do not just get a battery maintainer, these do not have enough current to really charge a battery.

These are nice chargers, they will actually "maintain" as will as I have been using mine on one vehicle and if I open the vehicle up, it will automatically kick back into charge mode when it sees the battery Voltage or Percentage of charge drop -
