Electrical problem
1993 Jeep CJ5 4 cyl Two Wheel Drive Manual

I have a Jeep CJ and I am not getting any lights or electricity on the dashboard, nor the headlights, nor the brake lights. However I can start the engine. I looked at the fuses and they are all OK. Could you please tell me what the problem might be? Thank you in advance for your time.
