APU red/yellow Light Troubleshooting 

Solution that worked for me is keep things away from where he pointed out, change your filter accordingly, check your oil level and top it off with regular motor oil, and check your APU fuse box. If your fuse box under the bunk and turn on the APU look at your open fuse box. After you start the unit, there should be normal blinking green light. If you find a fast blinking green light, then you have a blown fuse. Thank you man I had a multi problem.

Awesome!! Thank you!! That worked like a charm!!

My box with the filter in it is bolted to the ground with the filter right against the back wall for some reason

At the end what was the problem dude? Were u able to fix that?or shop?

Bonsoir frangin comment vas-tu et les activités c'est très très important pour Les jeunes du métier bonne soirée à toi

How the will it detect that the blower cover is not closed?

Heats!!!

Funny like plug I. Computer no software mentioned. How he actually fixed is still mystery.

Doesn't the apu run off fuel from the truck because i dont know any motor that runs like that thats not using fuel

Je suis interested pour le métier

Blind leading the blind. The board not fuse box
