richard5933 Report post Posted November 11, 2019 Welcome to the forum. It would be helpful for us trying to help you if you could provide more information. What make/model are you talking about? What troubleshooting steps have you done. Have you done any preliminary diagnostic measurements yet? Share this post Link to post Share on other sites
rayin Report post Posted November 12, 2019 Until you can get it properly repaired, use a set of jumper cables between battery banks when on shore power to charge both banks at the same time. Share this post Link to post Share on other sites
wolfe10 Report post Posted November 12, 2019 But, do NOT use jumper cables while driving. Both ends are HOT and if it were to jump off and contact any surrounding metal (read that ground) a fire could result. If we know what coach you have or how it is wired, there are a number of reasonable diagnostics that you can preform with a simple, under $20 digital voltmeter. And if we know what coach you have and how it is wired we can suggest some safe work-arounds that will allow you to drive. Share this post Link to post Share on other sites
rayin Report post Posted November 14, 2019 Brett, Thanks for emphasizing not using cables while driving, I just said "while on shore power" which can easily be overlooked. Share this post Link to post Share on other sites
