My check engine alarm comes on sometimes when I am acceleratiing and triming out and lowering my hydraulic jack plate at the same time. My merc monitor shows nothing but the alarm rings until i push exit on the lowrance.
I have a large deka agm battery and the voltage drops from 14.2 to 12.2 on acceleration. I have checked battery connections all are tight and have lock nuts. Could this be a battery problem? Thanks!
