The connector is the same as Hervey's, it's also a GM alternator. I dug out the sense connector and crimped a wire to it, hooked it to the battery post. My results are somewhat better than before but still haven't solved the big drop with the AC - this time I have no drop with my lights on but still the big drop with the A/C compressor. Maybe my original compressor is going bad? If not then I guess it's time to try the DMCH alternator.
