Not that kind of terminal.  Turns out the issue with the Motorhome was related to a couple of overworked and poorly located wiring terminals.  When International built the chassis they ran independent circuits for both the Engine and Transmission Control modules all the way to the battery.  This gets them the “cleanest” power for the computers.  In this location it is subject to the corrosive gas emitted by the batteries and the dirt, road grime, road salt and water that splatters the underside of the motorhome for 6 years now.  The issue presented itself when the motorhome would unexpectedly quit as if you turned the key off.  Turns out it was exactly as if you interrupted power to the computer when the connector failed to transmit the power it needed.  Though some helpful and knowledgeable folks at the Escapees RV park we were directed to a very good mechanic.  Took him about 20 minutes to diagnose the problem and after a few wires splices sealed with heat shrink material we are again “on the road again”.
