Hello I'm not sure if this perhaps would be better suite for the electrical section but here goes, I have what I think is two seperate issues in my motor home. The first is that I have for some time now to have to jump the fuse that goes to the ignition to get juice, but lately that fuse blows, I have done a trace but can't seem to find an open or short, is there something I can try with just a multi-meter? Here is a photo I took that shows where I have to jump it, the wire is not connected now, so I drew a couple of red circles and a blue line to show where it goes.http://i72.photobucket.com/albums/i174/wealthwise/fuseblock.jpg
The second issue is with the house battery itself, it's a new one so it works just fine but, when I have my shore power everything works, but when I have the shore power disconnected and the house batter is connected, nothing but the switch for the generator works, the strange thing is that when I disconnect the red wire that goes from the isolator, everything seems to work, I don't know if this a short or what or is it just wired wrong? Here are couple of photos I took it should be self explanatory. http://i72.photobucket.com/albums/i174/wealthwise/DCAM0147.jpg

Any suggestions or observation would really help.
Thanks

It is very difficult to offer an opinion of an electrical problem by looking at a picture.
The circuitry needs to be manually traced out.
The solution to why you can power up the circuit in the top pic by shunting off the fuse would depend on what those circuits do.
Is the blue wire part of the circuit that the 15 amp fuse supplies or is it a different circuit?
Maybe the connectors on the back of the fuse block are bad.
Bypassing the ignition could mean that the accessory portion of the switch is defective.
An observation on the last picture is that the circuit breakers next to the blue battery isolator have overheated or corroded connectors.
What you need to do is get a general schematic for the make and year of the chassis and trace out the circuits.
Oh ya, for a minute there I thought I had lost a month! :D
