Intermittent Error Code 77

Working on a low hour (under 200) unit. When aggressively pulling the lift lever a fault code 77 appears at times. A friend of mine is working on it in our shop... I have not seen it yet so I am guessing that it is an AL 077 on the display. Clears with rekey. He tells me that he has replaced the lift pot already. This truck has the premium display and Zapi controllers. Ring any bells, guys?

check voltage at battery when under load drive and lift at the same time, if voltage drops below 30v this will cause errant codes
