Black Tank Monitor
Made the trip from Kerrville TX to Big Bend… When I left Kerrville Black tanks were showing 20 percent it was all fresh water I added to rinse the tanks… and then I added some TST for the trip… When I got to Big bend tanks were showing empty but seals were holding..ie nothing leaked out on the way because when I opened the tank it wasn’t empty.
I have flushed them twice in the last couple of days and can’t get it to read anything higher than empty…. I have done a hard reset of the techlink computer under the bed. Any Marathon owners have any other suggestions…
