So a full service the other day which included draining and refill of the cooling system. This has led to another airlock which I will fix with a new water pump, temperature switch and replacing the thermostat. However driving it home in traffic the only way to keep it cool was windows open and heater on full blast - not ideal but got me home.
Now to the electrical. It was dark so the lights were on and fan on full blast. The gauge was reading about 8v with the fan full blast 11v just the lights and just over 12v with nothing on at all
See picture below showing the alternator you will see it looks ok shape but who knows. Battery is less than a year old so that is good.
So where to start. My instinct is telling me get a new alternator and maybe see if there is a more uprated version to add some much needed boost to the electrics but will I simply end up cooling something else with that.
Your thoughts and experience welcome. I will then tackle the electrics ready for the spring time as will be dong the cooling pump first.

With regard to the alternator, fitting a heavier duty one won't fry anything but it will probably be pointless as the car will use a certain amp/hour when running in normal conditions and the correct alternator for the car will cope with this.
I wouldn't buy a new alternator until I was sure the old one wasn't working correctly.
