Out of town Easter morning and 200 doesn't want to start. All accessories functioning. Will intermittently start....maybe every 4th try. Batt tested good. Seems to start more "consistently" with jumper cables hooked up to my 100 series and being rev'ed. Even switch batteries with no change. Any suggestions would be helpful in trouble shooting....trying to avoid a 100 mile tow to the stealership and still hunt Easter eggs with the kids.
