So I'm struggling to figure out this issue and can't quite find a thread that describes exactly whats going on with mine. I got my new motor built and dropped in. Now on first startup it was running weird and rough(very rich 10.4) so I checked on ECMLink. In link it was showing 6.4v for the battery! So I multimetered the battery with the car off, 12.6v. Car on the battery is at 14.7v, then I tested the alternator while idling around 1000-1300rpm and got 14.8v. I have double and triple checked all grounds, even added a ground from the alternator through bolt to the chassis. If I leave the car running to full operating temp, the battery voltage in link never gets above 8.2v, even with the alt putting out 14.8 and the battery sitting at 14.7. Does anyone have any ideas on what could cause this? Thanks in advance, this ones got me stumped
