frank3600 Report post Posted February 4, 2015 Has anyone towed the Chevrolet Colorado 2015 four wheels down. The manual says to disconnect the battery cable and make sure that it do not touch anything. My question is? Is this this to prevent running the battery down or something else, the manual doesn't say. Share this post Link to post Share on other sites
majfrizz Report post Posted February 4, 2015 I just went thru this when they installed the base plates on my Canyon last month. Someone found out it has to do with the electronics in the new power steering unit. It is only on the trucks (full size and mid) not on the Malibus, Equinox or Terrains. I had them install a battery disconnect with a charge line for the power for the Air Force One brake system. I turned it off one night for 12 plus hours, all I lost was the MPG ratings. no radio presets or clocks. all is working so far. Bob Share this post Link to post Share on other sites
frank3600 Report post Posted February 4, 2015 Thanks Bob for that reply I couldn't figure why the manual said to disconnect the battery without giving a reason like start vehicle to prevent the battery from running down. Still waiting on my base plate from Roadmaster, got a call today it should be ready next week. Anyway thanks again for that info. Share this post Link to post Share on other sites
teepee51 Report post Posted February 5, 2015 Bob, How is the charge wire hooked to the AF1 and does it also activate the brake lights? Thanks, Teepee Share this post Link to post Share on other sites
majfrizz Report post Posted February 5, 2015 Teepee The brakelights get the power from the RV. Share this post Link to post Share on other sites
teepee51 Report post Posted February 5, 2015 Okay but how did you get power to the Air Force 1? Share this post Link to post Share on other sites
teepee51 Report post Posted February 5, 2015 Also, the disconnection is to overcome the steering column, not the power steering. Share this post Link to post Share on other sites
hermanmullins Report post Posted February 5, 2015 TP, The charge wire is connected to the Battery so it will not be discharged each time the AF1 is activated. If wired correctly your light will be on a separate circuit. Your Tail Lights, Stop Lights and Turn signals must be on an isolated line through diodes. If you wire them directly there will be feed back and can destroy electric circuits. Herman Share this post Link to post Share on other sites
