battery goes flat

[John1.4]

i still think it's a drain somewhere though, could it be a short through stalks or one of the relays? when i tested it it was drawing .3A from somewhere, but no joy with fuses

got it started with a quick (suspiciously quick) jump from the rents scenic, literally 20 seconds and it was ok to go, so took it for a rag up the hills, and i've disconnected the battery to see what happens now, if it does go flat again i can say it's the battery, if not then it has to be something else surely?

considering just taking it to the local car sparky and letting him sus it out,
