Alcohol interlock
I have a 2012 Chevy Impala I just bought used with 88500 miles. I had to have an alcohol interlock device place on it. For some reason the car doesn't deliver constant power to keep the interlock signal constant...therefore generating an a "start vehicle" alert while I'm driving. Does anyone know if the car exerts intermittent power to its electrical components...such as powering down when car is idle or not being accelerated? Interlock manufacturer stated that it needs a constant 150 volts not to lose the signal. I previously had the interlock device in a 1999 Camry with no issues. I know this is an odd topic but any input would be greatly appreciated.
