OK here's an easy one...
When my air compressors kick on (with or without the car running) the voltage at the battery drops around 1-2v. With the car off, volts go down to under 12v pretty quickly. With car on, volts struggle to stay above 12.3 ish
Volts when alternator is running = 14v
Dual odyssey group 34 68aH batteries. Fully charged 12.8-13v
130amp alternator (17 years old).. I have a 200amp (or so they claim) sitting around I've been meaning to install
Wire run summary: 7 feet of 2/0 welding cable (battery to SafetyHub) + 9 feet of 4 gauge welding cable (SafetyHub to circuit breaker panel) + 2.5ft 6 gauge welding cable (from breaker to compressor)
