What is load-shedding??

load shedding means his battery voltage has dropped', so the truck will automatically "shed" the load of unecessary electrical equipment.. chances are after he heard that loud "beep" and saw the message, things like his lights, radio, and a/c turned them selves off.. all he has to do is start the truck and idle it for a few minutes to get more juice back into the batteries.. don't let it load shed in the winter on a cold day, chances are the truck won't start.

Here read some of this , it may or may not help ...

 

If all of your batteries are in good health it would typically take more than a day for a load shed to occur unless you are running something that's pulling a large amount such as a microwave. If the batteries are not holding up for a day or more while running small items such as chargers, TV, laptop or a dc cooler then you probably have a bad cell in one of the batteries and it will need to be replaced.

 

If the batteries are good, it should still start in the winter time after going into load shedding.
It's basically a low voltage cutout. Shutting the batteries off to almost everything except things needed to restart the truck.
On Volvo's the cutout point and alarm is usually set at 11.6 volts which is enough to start the truck down to approx. 20 degrees if it starts in reasonable cranking time.
If happens much, I'd be checking the cold cranking amps of the batteries.
It always made me nervors knowing my batteries were that low and I'd start it up immediatly.

 

I have had load shedding only a couple times, once when i had the key on and the idle shut down occurred and then after a few minutes load shed. Other time was during a 34 and I didnt start the truck the entire time so after a day and a half of running my laptop, fan etc it finally had a load shed so I idled for a few minutes then was good again.

 

If using a microwave, he might have to let the truck idle some while he is cooking, they pull a lot of juice.

Also a battery going dead may smell like a rotten, sulpher smelling egg. If they change out one battery, it most likely won't be long before the others go.

 

here is a question I never found an answer to, does anyone know how long you need to idle to get your batteries back to a full charge?

 

The Prostar I drive with auto start will run about 60-70 min at 1000 rpm when it recharges itself. Like using ac heavy on a reset etc...

 

It takes about 3-4 hours with mine.
