Battery drain - cause?

They may have backed off too much after breaking the first one. Definitely check all mounting bolts maybe with a hand ratchet wrench and extension. If you can tighten anything without much effort you may have round your noise.

Yep that has crossed my mind! I'll get my torque wrench out too. Again, thanks for your help and advice! Will post up with what I found out. Probably Wednesday, needed a day off after working 13 days straight. Not full time every day, but enough to want a break!
