Fix the loose battery terminal before considering the starter. The tick-tick is usually caused by a lack of battery voltage. The solenoid pulls, voltage drops too low, solenoid pops, voltage recovers, solenoid pulls, and so on.

There is available a battery post cover that makes it a little bigger so the terminal fits snugly. The post can shrink in size from sandpaper cleanings. First of all, try pushing the terminal all the way down on the post as described above by OdyinNH.
