2014 Evolution question(s)

Company Truck?
It's likely setup that way because they don't want you to idle..
Some have a Temp Sensor and they will idle at certain temps.
You can try releasing truck brakes with the trailer brakes set, it might idle a bit longer that way.


The Beeping..It has a low voltage shutdown, once the voltage drops to a certain level it shuts of all the accessories so you don't completely drain the batteries, and can still start the truck.
Sounds like you might have some bad batteries, or you're just trying to run too much with the truck off.

 

I don't know..depends on how the company has it setup..ours are supposed to be at 0...
So that would be my guess.

Idling or driving...the power comes from alternator...and 13.5-14 volts is about normal.

 

What company is this?

 

That says it all.

If leaving the tractor brakes released with the trailer brakes set or using your cruise control button to set it on high idle doesn't work I think you are S.O.L., son.

Find a better company, let me rephrase that: just find another company, you have a 99% chance of it being better than Swift.

What area are you in? Let us help you.

 

Anymore companies are setting them to shut off even if the brakes are released. Had one shut down on me once while backing into a hole at a receiver. Almost got a broken wrist out of that one.

 

One guy I know uses a hair dryer plugged into his inverter on the temp sensor to make the truck think its 120f out and thus needs to idle. That being said, something is wrong with your batt cutoff. It should not cut off until 12 volts (+/-.5v). If you have real bad batts the wabasco could be killing them.

 

I don't know if this would work, but it's worth a shot. Track down a snap on or Mac tool truck and see if they still sell a tool for depressing the brake pedal. Set the tool on your throttle peel so it idles slightly higher, say around 800 rpm. The brake pedal tools used to be sold for doing alignments on cars, don't know how much they cost. I did have a truck a long time ago that after looking at the throttle I figured out a way to jam a penny in the throttle assembly that would hold the pedal slightly depressed, it would hold the idle around 1100 rpm.
