Alternator quit charging took it out and they checked it, it was putting out 14.2 volts working fine. Went home and checked voltage, big battery wire had 12 volts. Other three wires have nothing with key on or off, one of them is a one wire plug which I assume is the idiot light, the other plug has 2 wires going into it. No power at them either. Help?

Did you right click them and choose "Save Image As"? I do that and they're beautiful.

These are enlarged diagrams of the charging circuit. I do not know which engine you have so I have included both.
