It is important to make sure this recall was completed (picture of my BCC “post recall” is attached). Note the “chassis switched” terminal has no cable on it and is taped up. The cable that was on chassis switched terminal (which is your engine ignition and starter related battery cable connection) is now moved over to the “Chassis Battery” terminal......which is direct connected to the chassis battery + terminal. So basically your engine is now hard wired connected to the chassis battery (you don’t need to turn on chassis disconnect at the door like a normal pre-recall 2013 ACE would to start the engine).


Note: If the recall was “not done”, if your chassis disconnect latching relay failed open while driving, especially at night, the engine would stop with resulting instant loss of various critical functionalities. Also note that after the recall is completed......the chassis disconnect relay (if it is working OK) in the BCC, still would control various chassis battery fed loads that are fused from inside the BCC (like steps, fog lights if equipped etc).


Since you say the BCC chassis latching relay has been bypassed......everything is on always; it is possible that this RV shop just placed a jumper cable from the "chassis switched" terminal to the "chassis battery terminal". This would hard wire the chassis battery to the engine ignition/starter cable as well as bypass the chassis latch relay inside the BCC. So in that case engine would behave safely ( would be like the recall was done) and all the chassis battery loads fused from inside the BCC would also get chassis battery power all the time. Might be a workable cheap solution to not going inside the BCC at all. So cavie’s battery terminal disconnect solution would kill all chassis battery loads if this "extra jumper" was in place, but you would have to go into the engine bay to switch off/on as required. A cheap solution for disconnecting chassis battery loads and even a failed open chassis disconnect latch relay).....OldWEB, you might try this to bypass that flaky chassis bat latch relay in your BCC? One external BCC jumper; one cheap battery terminal disconnect, unless I missed something......not the first time.



Attaching the RV Custom BCC schematic as well. Note the Chassis Switched BCC terminal is marked “chassis ignition relay” (I think) on the BCC schematic (left side of schematic are the various terminals on the BCC box). Hope this helps.
