True. So make that three possibilities.
If something must be wired to the battery, then I agree the factory strategy should be altered.
If its basically stock, no reason to alter if its wired properly and the connections are in good shape. Of course continually sending high current through the alternator output wire connection at the bulkhead will likely cause damage there. So that definately should be inspected. Figured save all that typing for if/when DentalDart addresses the issue.
