Re: alternator, battery, water pump?

Pressure test the cooling system to locate and then repair any leaks.

10 volts on the gauge and the red battery indicator lamp ON, means that the fuse for the voltage regulator is good and the alternator is not charging. The bolt-on terminal on the rear of the alternator has a red 10ga wire on it. It must have battery voltage at all times. The push-in type connector on the alternator has one wire in it. It should have battery voltage when the key is in the RUN position. If there is battery voltage at the red wire also, your alternator is faulty.
