Dear all
Installed a Eberspacher d5 in to my yacht and the installation looks good etc... The d5 that I have has the separate water pump which connects to the wiring loom with the brown wired and the black/ White wire. These two wires come from a black control box.
When I start the heater the pump does not run and I have no power to the pump, I have checked the pump and it works fine.
I believe the issue is in the control box which I have not opened yet. Does this box have a separate fuse for the water pump?
This unit was purchased second hand with no instructions. I have got the instructions from Eberspacher and followed!
Any help would be appreciated.
