1997 2.3 4spd overdrive. I have total electrical blackout. All systems were working well. A/C was working but not very cold. I topped up A/C freon and compressor clutch started recycling very fast. I shut down the eng ASAP. I had overfilled freon. Drew down freon to proper amount and I could turn the clutch by hand but was stiff. When I attempted to start engine. Total electrical blackout. No noise, no lights and no guages, nothing. I checked all fuses, ok. Pulled all relays I could locate and reconnected. Switched external 50 amp fuses. Nothing. The reset button or relay for the emergency shut down which on scematic is behind the glove box but I could not find it. Any assistance would be highly appreciated. Thanks.
