    Hi any and all advice is welcome.

    2005 160K - Red Triangle - P0A80 only code.

    Pulled battery and just test on a multimeter the voltage of each module.

    Ends were at 7.88V rest at 7.95V-7.93V and one at 7.66V.

    Think I have one suspect module at 7.66V and also the concern the invert is over charging?

    Will do a load on each module this weekend.

    Thank You

    When you pulled the codes, what other codes did you get? You should get a code letting you know which block is "weak or failed"
