my battery bank and charger are fine. wrote 14.4 just because it tops there now and then when the charger pulses as soon as it takes of it drops to 13.8 and then slowly down to 13.6 then at some point the charger want to pulse again and it bumps back up to 14.4. Sry for the confusion I made in the first post.
gathering the diesel pipes again now, and tomorrow I will fire it up and vent the entire system. had a tiny tiny hole in one of the radiators, less than a mm in diameter, so i was able to fix it very easy.
But that hole must have adding air to the system when it was not pumping the water. And I haven't vented out the system after.
fingers crossed.
