Freightliner Classic wont start and no low air alarms alarm

How many volts does the BATT. show to have in them?

 

Little more detailed info please.

Does it turn over?
Do you have fuel?
Did you check if the fuel lines have any pressure?
Did you try using liquid fire to start it?
Did you check the air filter or exhust is not pluged?
Did you check you fuses?

things are simple

driving lights are on by park brake switch located in switch manyfold.

if park brake pressure is over 6 bar - lights are on.

If air pressure is low - u have multiple problems, including this.

ok, what is the pressure now? tank1 tank2?
