^^^^^^ I do that also. Turn off the main battery switch on the back or your car to charge it! I found out the hard way. I used to download my FAST ECU's internal data logger while charging the battery. Killed an MSD box & a FAST ECU doing that. I found my 16 volt charger was putting out over 20 volts AC! Bought another charger, same thing.
