I am getting strange (and wrong) readings from my BMS while the alternator is charging. The BMS reports cell 4 is at a very high voltage (like that 3.8) when the alternator is charging the system. I confirmed with my Fluke voltmeter that the actual actual voltage is closer to 3.5. Readings are normal and correct when the alternator is not charging. Any thoughts on what is going wrong here? I have the Renogy DCC50s connected between my starter and house battery.

I bet you have a bad connection. Either the balance lead has a bad connection or the bus bar connection on the terminal is bad.
