Bad battery, bad main power and ground cables, blown main fuses, security system in full lockout mode.

Yup, a catastrophic failure like this is the battery or very close to the battery. Start with checking the battery cable connections. Make sure everything is clean and tight. Then go from there. Hope that helps! Jim
