akdarnell Report post Posted October 16, 2018 (edited) We have 2004 gulf stream sun voyager. we drove it the a few days ago and all was good. when we stopped and tried to restart there were no lights on the dash and it would not start. thought it was a battery issue so purchased 3 new batteries and that did not help. we are able to start using the emergency safety switch on the dash. is there a safety kill switch that could have been hit and we do not know it. thanks in advance it has a 8.1 workhouse engine with Allison auto transmission the toggle switch is on the dash and it stated that if you put in a new battery hold it for about 3 seconds and try to start. if that does not work hold that switch and crank the key at the same time. that worked. I think that is using the coach batteries to start the chassis. Edited October 16, 2018 by akdarnell additions comments Share this post Link to post Share on other sites
wolfe10 Report post Posted October 16, 2018 akdarnell, Welcome to the FMCA Forum. Please tell us what chassis you have-- that will help. And, when you say it would start "using the emergency safety switch on the dash" are you referring to the boost/battery combine switch? Share this post Link to post Share on other sites
richard5933 Report post Posted October 17, 2018 You purchased 3 new batteries - were these all coach (house) batteries or both the coach and the engine start battery? If you did not change the engine start battery, then that could very well have been the one that failed. Share this post Link to post Share on other sites

kaypsmith Report post Posted October 17, 2018 Be sure to check all chassis battery connections including the ground connections. I trust that you did hold for three seconds to reset any type breaker. Share this post Link to post Share on other sites
