Elec problem 1991 LeMans (Daewoo Lanos)

[Omerjim]

My son bought this car for the fuel economy. It doesn't charge, gages dont work, radio plays and dash lights work. No cke light or other idiot lights. So far we have checked out the battery, alternator, and all the grounds we can find. The alternator works by jumpering it to the battery.
I've done an unsuccesful search for a wiring diagram. Any help finding a diagram or help diagnosing the electrical problem would be greatly appreciated.

Problems are fixed. It was the dash cluster, we removed the dash cluster and observed several cracks in the printed circuits. These were repaired using a rear window defroster repair kit (a type of glue that conducts elec) reinstalled the cluster and all is well.
