Electrical Problems

Well I have an 98 Isuzu Rodeo V6 4x4 Ok here my problems the power locks work backwards. Starting the car it will unlock the doors and shutting off the car will lock the doors. Next I have no power to the radio, clock, and interior lights. Help!

Two things come to mind:

Haywire in the alarm system

And, how old is your alternator??

Any funny lights on your dash?

i would first start by checking *all* the fuses, including the non-'relevant' ones. not just a visual check, but pull out and check with ohm meter.
what about exterior lights?

any a/m components installed
