    Anything else you are not telling me? Because right now all i can think of is a new battery, there are other cases wherein every fuse existent to your car and man-kind blew up. Worst case scenario would be a burned ECU

    So far I have found that the reverse polarity protection diodes(one in fuse panel under the hood and one under ths dash) are fried. Where can I find replacements?

    Look for a fusible link on positive battery cable and or/and with this terminal disconnected run a continuity *OHM*
    test between terminal clamp and alternator bat post terminal

    That would close in on it also. This test will uncover an open circuit.

    Replace the 175 amp mega fuse located at the rear of the engine, center of rear valve cover under the coil bracket.
