I have the smart dcdc 18amp charger and my daughter has a vehicle with a smart alternator so after reading the book and trying to understand I have a couple of questions if someone could answer please.
1: do I just use the software to do the setup
2: do I just use the ignition setup and run an extra wire so the charger picks up the ignition when turned on
3: do I use both.
now from what I can see her vehicle drops below or battery voltage as when it’s running I read 12.8v at the battery and when she turns it off it drops to 12.75v.
