Manual Electric Scheme Ford Orion

Hello everyone. Greetings to all.
I'm new to the site.
I need the electrical manual for a 1997 Ford Orion single-point injection.
The head gasket blew, and the car was out of commission for almost two months.
Now that I've replaced the head gasket and reassembled everything, nothing happens when I try to start it.
The check engine light comes on, but the battery light slowly goes out, then flashes brightly again and stays on, barely. I replaced the battery terminals. I also installed a rebuilt starter motor, but still nothing.
I don't know what else to do.
If anyone has had a similar problem, I would really appreciate some advice.
Thanks in advance, and greetings to all the members of this site.

First I would ensure that the battery is loaded and in good condition, if you cannot control it, try that of another car. Also check well the cables chassis/motor.
