Ok..New batt, alt, belt has been replaced/adjusted. Multimeter reads 11.7-12.7 while in idle with all accessories off. However, if the lights are on or defrost on...etc(including the radio, but it needs t be loud as hell to even notice the difference) the voltage plummets. I mean as low as 4 VDC. If I'm actually out and about she'll die me fast. "Haynes" isn't much help, so can any one out there figure out the common place where they would all tie together? I thought about the voltage regulator, but have no clue how to bench/or on unit check it. Any ideas? Fuses are all good too; at least the ones under the driver side dash and the fuse box under the hood.
