Sorry for the late reply, just saw your post.
The connector plugged directly into the water pump is what I would try first. Grab some CRC QD Electronic Cleaner and try spraying down the connector to clean it out and then try clearing the codes and see if it pops up again. You could also try re-installing your stock coils, if possible, and see if it goes away. Im still on stock coils, so Im not sure how aftermarket ones would effect your battery, but its possible. It could also be your alternator or alternators voltage regulator aren't the correct specs
