Pull the plug off the CPU. Find the Yellow wire with the Blue stripe on it. It's on the top row, near the middle of the plug.

Put a ground on that wire. Turn the key to ON. The Idiot lights should all come on. If they do come on, then your problem is the alt relay in the CPU OR the small plug on the back of the alternator is off OR the white/black wire on that alternator plug is open to the CPU.
