But l think the alternator bit is least of your worries right now. The thrown belt stopped waterpump working. Have you checked the waterpump hasnt seized?

Thanks for your help, hope you had a good day!

The cog for the water pump seems to be turning so hopefully not seized?

Does it feel smooth when you rotate it?   (check both pulleys rotate easily and smoothly)

What did the belt look like? was it shredded or did it look curly - like it had been melted

but red lights mean STOP! immediately, not eventually! 

 The flashing red light in the temp gauge has two functions ....
 1. If the gauge is above 3/4 and it's flashing it means over heating 
 2. If the gauge is below 3/4 and it's flashing , it means low coolant in the header tank. 
  
 If it's says low coolant , and you can see the header tank is full to the brim ( not the number plate flap top up tank) then it's an electrical issue , and simple fault diagnostics will need to be employed ! 
  
 Red flashing coolant light self tests when you switch the ignition on and then goes off ......
  
 The system is very simple....
 The headertank ( the one in the engine bay ) should always be full to the brim, and the top up tank ( behind the number plate flap) should be full to the max mark when cold. When the engine is up to normal running temp the coolant expands and is pushed into the top up tank, when the engine cools down the coolant is sucked back into the header tank

Just to clarify, by header tank you mean what I have called the expansion tank - which is cracked?

The gauge was indicating empty and flashing.

Mocki wrote: ↑08 Apr 2021, 20:32 The DoPs (Dynamic Oil Pressure System ) is not a oil level warning it’s telling you that you have low oil pressure 
If it’s working correctly it will start shouting once you Rev above 2000rpm .

Normal advice is to get the oil pressure checked before driving it .

however, as you have just experienced a water pump belt issue, where the belt shredded , I would suggest you maybe have a disconnected or damaged wire where it connects to the pressure switch , just behind the water pump pulley . You are looking for a brown wire with a right angled spade connector on, which may or may not be connected to the pressure switch .it’s common for the belt to whip it off or damage it if it shreds
