Tammie, First , Welcome to iRV2, sorry you're here with problems and if I'm reading your posts correctly , you are having to try and get info for your husband who is away from home and somewhere with no internet. A less than ideal situation.
You filled out some of the coach info in the "about me" section when you signed up, but if you could take a few moments and , in the " Quick Links " drop box under your welcome message, click " Edit Signature " and fill out info on the coach , including year, and chassis manufacturer if you know it. Then click save at the bottom of the page, and the info will appear below all your posts automatically; as mine does below this one.
A few questions.
Are the interior lights and furnace working in the coach ?
Just need to know that he's not out there freezing overnight.
Does your husband have any tools for electrical work ? A voltmeter?
Is he at all good with automotive electrical?
Does he do any of his own repairs?
