Customer fitted the wrong battery and melted his e-brake cable - Fixed

Quite an interesting problem - the truck kept cutting out and was slow to move? Turned out that the customer had fitted a budget battery and unbolted the negative cable's mid mounted grounding tag to the body to stretch to fit - ended up with the negative current being pulled by the collect of the e-brake or parking brake cable - which then melted the plastic coated inner wire and locked up the prop-shafts - ended up adding a thick linkage piece to reground and of course replacing the entire e-brake assembly - That budget battery didn't work out to be a bargain after all.
