Hello, hooked up known functional, have three others installed, BatteryMinder trickle chargers/tender to the negative stud and positive cable under the hood. Unit shows correct polarity as well as charging. Unit never goes int desulfaction mode. When disconnected for a normal day of driving, the display in the instrument cluster shows an initial message, something like "excessive battery discharge". Delaer and BatteryMinder have no clue. Tried different BatteryMinder to verify and have the same results. I am planning to try direct connection to the battery to see if this cable coming from the battery has some type of monitoring that can not be bypassed. Any Thoughts?
