Place the positive (red) voltmeter clip on the positive (red) battery terminal post, along with the black clip on the battery negative (black) terminal post. Look in the reading displayed in charging volts. The charging volts must range amongst 14 and 15 volts. A drop below 13.8 volts indicates an issue using the alternator armature and windings.6Hook up an ammeter towards the battery, together with the engine off. Get rid of the wire from the terminal marked "B" on the alternator and connect it towards the unfavorable post on the ammeter.
