Alternator performance.

[oscar]

Correct me if I'm wrong, but I believe the RAM in my sig came with a 180A alternator. I plan on "feeding" a B2B charger. The bank can take any amperage, but I can't load up the alternator to max for three hours. Sooooo, the question I have is how much does the truck use while running? (Lets say I've waited 10-15 minutes after starting to take the peak load off the battery....) Under 100A? That would leave me 50 or so amp for the B2B......

Depends what your running in the truck but it usually wont be over 40amp unless you are running something at peak power

Like heated seats...... OK. Time to install an ammeter.
