Scott and Colleen Miller Posted October 17, 2022 Share Posted October 17, 2022 Dear Community, I have a 2004 HR Endeavor 40PRT. I recently had the transmission rebuilt by Allison. Picked it up from the garage, went camping and tried to lover the leveling jacks. “Nothing.” Discovered that the battery box 120A fuse keeps popping when I try to lower my jacks. I replaced the battery box wall mounted 120A fuse, looked everywhere for loose connections, and checked all fuses I can think of. Sure appreciate any and all help! Thank you, James Miller Link to comment Share on other sites More sharing options...
Harvey Babb Posted October 18, 2022 Share Posted October 18, 2022 Disconnect the cable at the pump motor and try to lower. If the fuse doesn't blow then you have a seized or shorted pump motor. Link to comment Share on other sites More sharing options...
