If you lift the red flap, there is another red cover underneath it.
If you lift this second cap, there is a metal stud. I think this is for a positive connection to the battery, for charging and use of jump leads.
There is a negative stud on the top of the suspension turret.
This is my understanding, but if I am wrong, someone please let me know, so that I don't do any damage in later life!
