Battery terminal contact problems at the battery post account for the majority of high-current problems. A first step should always be to use a battery post/clamp cleaning tool to make the sufaces shiny, then re-attach. Remove negative clamp first, replace it last. Battery post itself could also have broken internally, so replacing battery could be necessary if post cleaning doesn't solve the 'wiggle' issue.
