Sentra B12 (Classic) '93: Electrical problem

Hi everyone;

I have a major issue with my Sentra Classic '93. Shortly after someone fixed a minor electrical problem " the gauges + lights stopped working", the car completely failed " No Start". The garage I towed it to says there is no power going to the computer, but they need the electrical drawings to be able to troubleshoot it. The problem is that they can not find the correct drawing for the '93 Sentra Classic - B12. Even the Nissan dealership here in Toronto that they contacted could not find the schematics.

I wonder if someone on this forum has ever have had a similar problem , or would know how I could get the proper schematics or service manual for the '93 Sentra Classic.

Thanks,

Hi Nick,
Thanks for your message. I think that what I need is the ecu diagram and /or how it is connected to the other parts, ex,. ignition coils, grounds, etc.

Thanks again, Alex.
