Wiring Diagrams
Hello everyone, new user here and I'm posting on behalf of my dad who owns a 1993 Cobra, Phoenix. I know it sits on a GM P30 chassis and has a 454 motor. He uses it a lot and just completed a 7,500 mi...

Really depends on what wiring diagrams you need.
If it is for the chassis Chiltons Manual 28642 has drawings. They are pretty basic. Not many strange items in P-30 chassis.
Your other posting says he is having alternator failure. That coiuld be caused by battery control center and fusing issues.
The P-30 with the 7.4 engine charging system on our rig has eaten two alternators in about 180,000 miles. Problems were caused by operateor running down batteries and charging using the alternator rather then starting genset to charge through converter.
Another issue that effected the charging was the battery ground connection. It was attached to the intake manifold under the air conditioner. It did not get serviced so it corroded severily. This got corrected by moving the ground connection to a better location.
I would start by checking where the battery control center ties into the coach battery system. Look for a bad connection and possible a ground in the positive lead.
Locate battery control center and post make and model.
