Check the battery terminal voltage when the starter is engaged and trying to turn the engine. If there's a severe short internally, the voltage will be very low- - - - -3-4 volts or less. The cables will also get hot quickly. If there's a high resistance connection in the starter such as one of the brushes making poor contact or an oxidized surface on the commutator, the terminal voltage will drop slightly or not at all due to low current flow. Normal cranking voltage on a 6 volt system is usually 4.5-5 volts with the engine turning at normal cranking speed. It sounds like there's high resistance somewhere in the starter. You could also try removing the spark plugs and see if the engine will turn with no compression, but it sounds like you need a starter.
