Since I am no electrician looking at the diagrams are somewhat useless hahaRe: Calling all electrical system sleuthsNot sure what a dvm is, but I have access to the schematics. The battery boost switch doesn't do anything when pushed. I was under the impression that it should cause the isolator to open (click). So perhaps the problems is there somewhere.Calling all electrical system sleuthsI have a 2007 Itasca sunova 35J house batteries charge when on shore power as well as when the generator runs, but not when driving. In a small compartment to the right of my steps are the two items. On the left in this compartment I have a silver battery solenoid isolator. I changed it out for a new one. It still does not click and doesn't charge my house batteries. To the right of the isolator is the battery disconnect. It does seem to be working. It clicks on and off and does disconnect the house batteries. I would post a pic, but not sure how to. I have checked the fuse on the relay and it is not blown. I don't want to take it in if it's any easy fix that I don't know about. Thoughts please. DavidRe: electricalThanks for all the insight. For those with a similar hookup is there a fuse that could be blown? If so can you give me a general description of where it would be and what it looks like. I know what a normal fuse in a car looks like, but think this one may be different.Re: electricalso it looks like that may be the problem. It makes no noise at all.Re: electricalWhen I push it on or off the house disconnect makes noise when I use it. When I push the boost button it makes no noise at all. Should the boost be making a noise when it is pushed?Re: electricalThe two solenoids in question are in a compartment to the right of the entry door. Too many wires connected to them for my liking to fix. I'm on the road right now so don't even have access to a part. At least I think I know where the problem lies though.Re: electricalI looked for a fuse, but think I may not have a battery control centerRe: electricalScott, Your description is great and it seems to be my setup. The battery boost switch seems to do nothing when I push it. I don't hear a click or anything. The house battery shutoff does click when I use it and it does shut off the power in the house. It's looking more and more like it may have something to do with the battery boost switch. I'm not sure where that solenoid is actually located though.electricalI have a 2007 Itasca sunova 35J house batteries charge when on shore power as well as when the generator runs, but not when driving. I've looked through the web and found that it's possibly the solenoid? There is a click when I push the auxiliary battery button....thoughts. Thanks!
