Might have touched on this in another thread, but since I installed a Redarc Battery Management System with a temp gauge on the Aux Battery, I have been very concerned about the heat from the exhaust. Around town I was constantly getting temps of 38-39 degrees, and during a test run where I worked the engine hard up some slow dirt tracks in 4WD, the battery heated up to 48 degrees.
Yesterday I fashioned up a bit of a heat guard and drilled some air holes in the battery box as well.
Also welded on half a chain link to the large pin that holds the whole battery box in place and allows it to swivel down. This pin was previously a pain in the ass to remove or to align properly when putting the locking bolt through it. Now works a charm.
I am a bit dubious as to whether this will make a whole lot of difference or not. If it doesn't, then I am down to doing something else with the exhaust or moving the battery.
