I have this setup in my motorhome. Attached are the pictures of the switch system. It runs the house fine when hooked up to elec. with the supply cord. When running on the generator it only runs the back half of the house. When running on the generator the top switch in the picture has juice coming in and going out. The bottom switch has juice coming in but nothing coming out unless i push down on the points in the middle of the switch. Also when im hooked up to the plug only the bottom switch is getting juice in and out but everything in the motorhome is working. Can you help me on this and tell me what i need for parts to fix my problem.
Thanks for any help you can give me.
