Yes thats where all of the ones I have seen are grounded.But the factory location has to be differant. If you look in the operators manual it will show a woven style ground strap coming from the battery going to the tab on the sliding battery tray left rear corner of the tray for gas &amp; the sliding tray is flipped around for diesel with 2 batteries so the tab is in the right front. so with the battery being grounded to the sliding tray the tray itself has to be grounded. &amp; if up look in the parts book they list a woven style ground strap with eyelets on both ends that in the discription lists it as ground strap from battery tray to block.So where did the factory mount that cable???
