Check if NO water in the radiator
Check Very low oil in engine – extremely low oil level
Check Very low fuel in fuel tank or fuel pipe is restricted, bent, damaged, hence not sending enough fuel through the fuel pipes to the engine. Could be dirt in fuel tank
Check Fuel pipe to the engine has broken and leaking
Check Engine is too HOT- Check radiator vanes for damage or full of dust/dirt/blocked
Check Coolant sensor failure – Control Panel display will show ‘low coolant warning’
These can fail at any time. Check the coolant pressure sensor appearance.
Check the terminals. They could be bent or broken as photo below.
Example of coolant sensor:
Example of coolant sensor terminals:
Replace the failed sensor and all should be well again. If replacing the coolant sensor doesn’t stop the problem of starting and then the generator shuts down, the next step will be:
Oil pressure switch failure –Control Panel display will show ‘low oil pressure warning’
These can fail at any time. Check the oil pressure sensor appearance.
Check the terminals. Check the connections are tight. Check the thin cable is still attached and not damaged or no breaks in the cable installation. If all these are correct then the next step is to replace the oil pressure sender.
Example of oil sender pressure switch
Replace the failed oil pressure switch as example above and all should be well again. If replacing the oil pressure switch doesn’t stop the problem of starting and then the generator shuts down, the next step will be:
Generally speaking, the above suggestions 1-7 will get your generator started again.
If you have carried out all the above advice and still your generator starts and then stops, your last resort will be to call in a control panel expert.
Re-program the generator controller panel to accept the new parts that have been fitted.
The coolant sensor and the oil pressure switch may require to be acknowledged by your generator control panel. You can do this by integrating the control panel, for example a Deep Sea Control panel 7310, and resetting the parameters for the newly fitted parts. If you struggle with this task yourself ,then better to call for assistance from your local Deep Sea Control panel expert or you local CoMap Control panel expert who will arrive with his laptop and plug into your controller to re-set the necessary parameters.
Now you’re ready to start your generator and happy days again.
