I recently bought this car, and it would only run with a boost off. So I changd the battery and still had the problem. Next I changed the alternator and my battery light is still coming on and eventually the car still dies on me. Any suggestions?

GENERAL INSPECTION
Ensure battery posts and cables are clean and tight. Check drive belt tension. Ensure connections at generator, regulator and engine ground are clean and tight. Check fuses and fusible links, replace as necessary.
NO-LOAD TEST
Connect voltmeter positive lead to B+ terminal on generator and negative lead to ground. Start and run engine at 1500 RPM with no electrical load (foot off brake and doors closed). Read voltmeter when voltage stabilizes. This may require waiting a few minutes. Voltage should be 13-15 volts.
