Cadet57 0 Report post Posted January 9, 2013 I could use some knowledge here.. I need to replace the House Batteries on a 400SY. Of the Four Batteries does anyone know which Two are the "House Bank" Some (idiot) prior owner replace all four last March with New Batteries...But, they cut corners and replaced them all with Heavy Duty Truck & Van Batteries (Interstate) so... they are out Deep-Cycle and will not re-charge effectively for "House" use.. But.. they seem to be fine for Engine Starting. Any help is appreciated.. Share this post Link to post Share on other sites

A process of elimination will determine which two are the house batteries. Your owners manual may help you out as well. Share this post Link to post Share on other sites
