In your picture you can see 2 large nuts and two small nuts, there should be 12+v across the two large nuts if it is working if only 12+v on one lug it is not engaging. Also check the voltage on the small nuts one should have a 12 v input to the solenoid. You can always jumper the 2 large connection to use the MH for your trip until you get a new solenoid.
Is this the right part to replace if my house batteries are NOT charging from the alternator and if I don't hear any click when I push the battery boost button on the dash of the coach?
Every MH is set up differently. So you need to look at your manual if you have one. On mine I have 3 solenoids/relays(I never know what to call them) If yours is not charging that would be the charge solenoid which can look different on each MH. My battery disconnect looks like the one in your picture, the charge solenoid is the hi tower one in Chris's picture. I replaced both of these from Napa. In either case if they are working they should read 12+ v on either side of the of the large nuts( across large nuts is bad wording). If you are getting the alternator voltage on one side and not the other then the contacts are probably corroded and need to be replaced. Mine were mounted on the firewall in the same box as the disconnect solenoid. If you measure the voltage on these nuts with the engine running and post them here it would help to solve your problem.
