House batteries are charged but wont work.
I have a complicated issue. When I try to run my house batteries the only way I've managed to get them work is if I hold down on my house battery switch. I have tried clamping down the switch in order...

Your house batteries are directly connected to the 12 volt fuse panel. It not complicated, but you have to determine what is going on.
With your voltmeter on the positive and negative terminals at the fuse panel, do a check. Do the same on your battery terminals. They should read exactly the same.
Now do the same voltage check when charging through the converter, again they should read the same.
Once you have done that, connect up with your jumper cable to your negative battery post, and the negative terminal on your fuse panel. If that makes it work, look for a bad negative connection. In my case, the main negative lead on the converter wiring terminal strip was totally loose.
If that doesn't help, take off the negative battery to negative terminal strip and do the positive to positive.
If that makes things work, look at the positive connections.
