I am not getting 12 volt power from the house batteries when using the store/use switch. The generator starts and powers the house 12 volt system. Checked the store/use switch with a multi meter and it appears to be okay. I found the solenoid next to the water heater. I will try to replace the solenoid and see if that is my problem. I replaced the blown 7.5 fuse with negative results. When I bypassed the solenoid, I got power to the house 12 volt system. It is a little frustrating in that I have 1,000 miles on my 2017 Vegas 24.1 and have already replaced the chassis battery. I picked it up a few weeks ago with a manufacture date of May 2016.
