Redarc DC-DC Battery Charger
I’m in the process of installing a Redarc BCDC1225D battery charger in my truck camper. I got it installed enough yesterday to give it an initial test, and was pleased to see that with the truck idlin...

This is on a 2016 Ford F450. It has the single “Extra Heavy Duty” 200 amp alternator.
I think it’s this one.
I located some additional info regarding what the “low voltage” trigger points are intended for. I’m not familiar with this type of system, but here it is:
Compatible with Smart Alternators
A number of newer vehicles on the market have ECU-controlled, variable-voltage alternators designed to reduce emissions and boost performance. This type of alternator varies its voltage based on the driving conditions. When the alternator voltage is low, the system can drop below 12.7V, which would deactivate a standard isolator or battery charger. However, with the Redarc BCDC battery charger, this is not an issue. Simply connect the blue override wire to the vehicle ignition and the charger will recognize that the car battery is still receiving a charge from the alternator, even if the voltage has dropped. The charger will modify its voltage requirements so that it can continue to pull power until the start battery drops to 12V, as opposed to the standard 13.2V.
I’m going to assume that the truck does NOT have this type of alternator, as I’ve never seen voltage drop that low on the voltmeters I have in the cab.
I understand your reasoning, and I’ll leave the blue wire disconnected so the normal on/off trigger voltages will be used (and monitor what it’s doing).
Thanks.
