Redarc 40 amp DC to DC Charger issue
After about 15 seconds or so when I start the engine my shunt reads up to almost 49 amps and then the 60 amp input breaker pops. Whats going on here? Isn't the charger supposed to limit the output cur...

I only turned the ignition on to measure the current briefly out of curiosity before I started the motor. The charger activates with a signal from the ignition. The output current is about 43A at higher rpms and 48 at idle like I said.
I was hoping it was your input current fluctuating. Very unusual for charge current to fluctuate like that based on alternator rpm/output. The whole purpose of a dc to dc charger is to stabilize the charge process.
Using the battery isolator didn't work. It didn't shut down so we connected the ignition wire and now it turns off with the ignition. Don't worry, even if there wasn't a warning beep when the ignition is on until starting the motor it's not something I'd forget.
