    With a volt meter across the battery and the car running, it says it is putting out 21V ? With it of the battery is reading 17V. Doesnt that seem kinda high?

    Either your meter is screwed up or your going to fry that battery quick. First I'd find a fresh 9volt battery and check your meter.

    Try another voltmeter. If u really have that much voltage I wud think u wud damage elec components.

    Measure the fresh 9v battery with the meter. A low meter battery should not alter the voltage readings.
