Hot Alternator

Don't you just hate it when someone thinks that an alt can "CHARGE" a large battery bank, and above and beyond that, come here to talk "smack" about your products, that clearly that individual was incorrect, and more or less was the reason for the "ALT" failure.

my batt bank is not that big, and im not talking smack. Im just saying what happn to me. Anyways im not going to talk about if anymore. Matt and I have had enough of each other.

In order to bring 4 Kinetik 1800's to 15.3 volts, you are talking about almost 80 amps worth of current with NO LOAD. Add the vehicle's stock amperage requirements (20 -30 amps) and you are talking about 110 amp load before you ever even turn on your head unit. You have to remember that a battery IS a load for an alternator if the setpoint of the regulator is higher than the resting voltage of the battery. The higher the setpoint is above the battery's resting voltage, the harder the alternator will have to work to hit the setpoint.

BTW, 15.3 volts will eventually ruin those batteries now that you actually have some amperage behind that voltage. If you listen carefully, the batteries will start hissing (gassing) after a few about half an hour or so.

Even charged batteries can draw 80 amps? I thought after they charged the amount that they drew fell substantially.

They do. Should be very little if your batts reset to 12.8, then there full.
