      July 10, 2019 at 12:26 pm Can’t trace my temp alarm cause. On the hard for 9 days working on the bottom. Ā½ hour back in the water and the alarms go off. Alarm comes on when starting dead cold, even replaced the VDO sender unit. Checked all fluids and flow with temps on both engines about the same reading with infrared. Been reading and following the forum for years and appreciate all your info.

      June 9, 2020 at 2:07 pm Did you ever solve this problem? I have the same issue on a 1993 GB 36 Classic with twin Cummins 6BT5 – 9m. I have run out of ideas.
