Battery Cables Against Air Line

[Old Scout]

While changing out the old MSW inverter on my 2003 MDTS (upgraded to an RS2000), I noticed the boys at the factory ran the battery cables [to/from the inverter] against the emergency brake air line. These cable have been tight against the air line for the last 75K miles. No obvious damage here but I rerouted the cables anyway. This is worth a check the next time you are underneath greasing your u-joints.

I'm not sure why that is a problem

I would be concerned about the chaffing of one moving against the other due to expansion of materials alone.

Dave & Colleen, your assessment is spot on. It might have been misleading to say the cables were "against" the air line. In fact, the cables had been looped under the E-brake air line and then pulled back up and secured tightly to the bottom side of the coach floor. The air line was pulled way out of alignment with the connection on the E-brake cylinder. While chaffing is an issue, I was concerned about the stability of the air line connection and the possibility of a E-brake deployment at hi-way speed. Ironically, air pressure releases the E-brake-- loss of air pressure deploys the E-brake.
