[QUOTE="chasfm11, post: 28506, member: 3606"] I have a 2018 Equinox that I've been flat towing behind an RV. Even though I have a charging line installed from the RV and have verified that it is providing voltage, the Equinox battery has gone dead a couple of times. I've tried to troubleshoot the problem but everything that I thought that I knew about batteries and charging systems does not seem to apply to this car I installed a battery monitor and use it when I'm not towing. It shows a constant 12.22 volts and a battery that is 66% charged. I understand that the engineers did this to try to preserve battery life. But is is really hard to figure out when I might be in trouble with the battery charge level when towing. I follow the instructions to put the transmission in neutral and it takes about 30 minutes while towing for the highest current drain items in the Equinox to "go to sleep", taking the battery voltage down further. I have very large wire feeding the Equinox from the RV and it comes (fused) directly from the RV batteries. I would expect to to charge the Equinox battery above its normal level after several hours of towing because I'm seeing 14.v+ on the charging line. The voltage monitor will show 12.55vs while Equinox is being towed. Driving the Equinox around town has no issues. Start/Stop works normally, even with what seems to be a low battery voltage. Ideas?
