hi to all, apologies that my first post is to ask advice on a problem, and im not very mechanically minded. i bought a 1995 tdm last week, and she had started ok for the first few times. however, when i went to start it two days ago all i got was the engine trying to turn over but seemingly no spark or sometjhing, and the more times i tried it, the lower the battery seemed to get. now when i went yesterday to try again all im getting is a clicking noise and the rev counter needle moves slightly. could it be the battery? which seems to be a nightmare to access as its away in below the petrol tank? how on earth do i get it out to charge it? maybe its something else that im not thinking of. Any help would be greatly appreciated, thanks.
