Hi thank you for your video. I have SOL HOLD andALT POWER light and I had fault engine overheating and it shut off unit couple of times but it starts and runs and stops after some time. Maybe you had experience with issues like this. Thank you. Vj.

@@vjm6238 check the oil level and make sure it’s at the correct level. Also look for antifreeze pooling on the ground under the APU. Could be a bad water pump causing the overheating problem.

Which lighs should be on during normal operation?I got sol hold and alt power light on, does it mean my alternator is bad?

@@nikoz4841just had the same situation and two lights come on. What did you do to fix it?

Ccu main breaker tripped unknown how to fix it any suggestions

[@Truckingwithcooper45]

@@Truckerjj1 you’ll need to take the bottom cabinet off. Under there is a reset switch. It’ll be a red button.

[@Truckerjj1]

@@Truckingwithcooper45 did that after watching the video still tripping it I guess I need to replace circuit board

[@Truckingwithcooper45]

@@Truckerjj1 check the main connection at the battery. Sounds like a ground issue

How would you go about bleeding the fuel line?

[@Truckingwithcooper45]

Need to crack open the nut running into the top of the injector and crank the motor. As your doing that watch for air coming out. Do this until it’s noting but a solid stream of fuel. Then retighten the nut.

Everything is fine except the AC unit won’t come on. APU running and controller is on inside bunk, AC or heat unit won’t start up

[@eddiehustle7446]

I have the same issue did you get it resolved?

[@marimavu]

Check fuses

SUPER THANK YOU.....

[@stevenwilson9678]

U should make a video on how to do orientation since ur a orientation specialist

[@Truckingwithcooper45]

Maybe I should

[@farmerclark]

What about no fuel pressure

[@Truckingwithcooper45]

That would indicate a failed fuel pump.

Put a rock on the fuel pedal and idle the truck
