Solution JeNkHat Posted July 3, 2023 Author Solution Share Posted July 3, 2023 Can you tell me where the salesman switch is again I did not have our electrical schematics with us and it’s a 2007 Link to comment Share on other sites More sharing options...
96 EVO Posted July 3, 2023 Share Posted July 3, 2023 Master disconnect switches they were installing have been known to fail as well! Link to comment Share on other sites More sharing options...
JeNkHat Posted July 3, 2023 Author Share Posted July 3, 2023 The master switch seems to operate the solenoid but still no change Link to comment Share on other sites More sharing options...
Dr4Film Posted July 3, 2023 Share Posted July 3, 2023 (edited) Salesman Switch is always at the entry door commonly called Battery Cut-Off Switch. Thats where mine is located. The solenoid for the Salesman switch is probably in the Rear Run Bay. Edited July 3, 2023 by Dr4Film Link to comment Share on other sites More sharing options...
JeNkHat Posted July 3, 2023 Author Share Posted July 3, 2023 We operated it several times, and then it started to work. Thank you very very much.😄😁😄 2 Link to comment Share on other sites More sharing options...

Thank you very very much.😄😁😄 Please define “IT”….the Salesman’s switch at the door or the main battery cut off? If it was the Salesman’s switch, then you might consider two things. First, you may (probably) have two solenoids….but check. The easy way if for someone to operate the master and hold your hand on what you believe is the solenoid. Then you can see if you have TWO. If they appear to be working …. They LATCH IN & LATCH OUT, there will be a fuse, maybe 2, on the top of each one. Pull and use a VOM to test the fuses….or replace. Next is to use a VOM and measure across the two large studs….set on DC. If you have more than 0.05 - 0.1 VDC on the meter, then the contact’s are pitted. Don’t know if they can be cleaned. This is NOT the BIG BOY or the battery boost….that one is larger and can be serviced. If all is well, then find the Main House Battery disconnect….with a full load, like running all three exhaust fans or letting the MH go on inverter, measure the voltage across the two studs….same deal. Also check the batteries for cable tightness. I PERSONALLY, due to the age of the MH, would shinny under the battery box(s) and trace the ground cables to the studs. Loosen the nuts slightly, so the cables will just barely rotate side to side and then wiggle them back and forth to clean things up. Retightening is next. Thees are the most things you do….when this happens Link to comment Share on other sites More sharing options...
