I am replacing the battery on my wifes 307. no problem I thought. until I discovered the negative "quick release" terminal clamp was so corroded that it was RS.OK, I'll put in another one I thought. not so easy as the cable is bifurcated and disappears under the fuse box. tried removing the battery box, removed no less than five 13mm bolts and then discovered there was another one holding it from OUTSIDE, UNDER the inner guard lining which involved removing the wheel, loosening the lining enough to get a spanner on it and finally finding the other end of the cable bolted to the body work.Then tried to locate a new one. no luck but learnt that it would cost $215 plus freight. F... that.I now have one on the way from a wrecker. I have run pugs for 40 years,(still love the 404) but sometimes I wonder....WHY overcomplicate what should be a simple time proven piece of design?
