Jackson,
Sorry about your plight. Since you are broke down, the fastest way to get back on the road is to call the Prevost Action Service System (PASS). They have excellent technicians, are always available and will walk you through troubleshooting procedures until the issue is resolved. Their number is 800-463-7738. Don't hesitate to call, you'll be glad you did. If possible, have a light and volt meter when you call. Let us know how this turns out.
