Question about 2004 Jeep Grand Cherokee
When the engine is running, and a volt meter is placed on the battery, what is the voltage reading? This is the first basic step to check the alternator output. Do not rely on the gauge, use a volt meter.
Also rev the engine to approx. 2500 - 3000 RPM, what is this reading?
With the engine running, again, place a volt meter on the battery, turn on all the accessories, lights,blinkers, heater motor. etc. What is the reading when all these accessories turned on?
