Air gauges droping out on rough roads
« on: March 13, 2012, 03:36:05 PM »
 My air pressure gauges get squirrely at times and warning light - buzzer come on while on rough roads. It corrects itself quickly. i do not believe i am actually loosing air pressure. It appears to be a sensor/electrical problem.

 And being from Louisiana, I have to travel on some pretty rough roads until i get out of my home state...

 Anyone experience these issues before?

We had the same thing going on when I was stationed at Ft Polk, The roads are horid in LA. More than likely you need to clean and/or tighten the sensor wire on the air tank..

If your Tiffin is still on a Freightliner chassis air lines go into the VDC (or MMDC) and the computer forwards an electrical signal to the dash. When our gauges start showing zero it usually means a loose VDC connection at the dash or I have to reboot the VDC by unplugging the connector for a moment.

Yes Jeff, it is a Freightliner.

I pulled the dash off and it seems the gauges actually have air lines conected to them. I traced the lines back to a manifold looking thing of sorts. It seems as though the gauges are ran by air. The warning light has a little clip with about 5 little white wires, it apeared a little loose but all else looked good.

Everything I have read talks about digital signal to the gauges. Sort of confuses me that the gauges have air going to them.

I really apperciate the feed back. I will check deeper into it with the information you have given me.
