Planning for AC loads

Driving the truck while operating AC and DC loads
Recharging Driving your truck does not guarantee that the battery is being fully
recharged by the alternator if you are running a combination of large AC
and DC loads.
The alternator must provide more power than the combined DC and AC
loads draw for your battery to fully recharge.
Example This example shows what happens if the alternator is overloaded.
Figure 2-2 AC and DC loads powered by the alternator
The alternator is charging at 130 amps while the truck is being driven at
highway speeds and there is a 1000 W (AC) load.
