> New Battery- New Alt (bench tested at 15V twice)
> Voltmeter on dash says it starts up at 12V.
> Battery checks the same 12V
> Big terminal on Alt check same 12V

> All three points check the same readings, even as the volts start
> droping down to about 7-8 volts. As it goes down you have about

> Charge Batt & away we go again for another 10-20 minites

> Checked & cleaned as many ground wires were accessable. Big one on

> Checked terminals at starter R & S + big positive cable.
