Answer: The BG PXT®2 Performance Exchange® for Transmissions is designed to work with DC voltage between 11 VDC (volts of direct current) and 14.9 VDC with good power supply connections. If the charge is low or the connection is bad, the BG PXT®2 will not operate properly and will potentially turn off.
Typically, the power supply used for the BG PXT®2 is the vehicle’s battery.
NOTE: An automotive charging system should be between 13.5 VDC and 14.5 VDC at idle with no loads. If the voltage is below 13.5 VDC or above 14.5 VDC, then the charging system might not be able to keep the battery at 100 percent capacity.
