I suddenly have a no starting seeming dead battery situation. The engine, 454 and the generator have no starting power. The battery is fully charged. I also have no headlights or other exterior lights. As if the battery is disconnected. Here is what I noticed two days ago. I have a wire under the dash that has been tapped into. When I bumped against this wire, I could here something in the inverter panel click. As if a solenoid was clicking. I pulled the electrical tape off the wire and saw an ugly loose spice and the wire appears to come straight off the ignition. Last night I opened the inverter panel to inspect the panel and measure some voltages and check all fuses. What I believe is the red battery wire coming in has zero volts. What I believe is the coach battery red coming in has 12.8 VDC. I also checked all the fuses in the inverter and the fuses on the inside of the firewall. I do not know if there is a fuseable link on or along the battery cable somewhere. My guess is that loose connection under the dash continued to make and break the connection after I let it go two days ag, This lead to maybe a fuse link or maybe the relay between the coach battery and engine battery burning up. Its a 1977 Airstream 454 P30 chassis. Any thoughts ? ideas.
