What's wrong?
The Sure Power battery separator in 2009-2011 Showhauler Garage Coach, Motorhome, and Toter Coach units is part of the electrical equipment. Its job is to manage the connection between the vehicle battery system and the coach battery system, so charging power goes where it is needed without leaving the main starting battery drained.
On affected Showhauler units, the Sure Power separator can overheat during use. Excess heat inside this device means the electrical component is no longer working within its intended range. The recall centers on that separator device, not on a routine battery maintenance issue or an owner adjustment.
There is no warning sign before failure. Do not rely on a dashboard light, smell, or charging symptom to tell you the separator has started to overheat.
