Prairie 360 turns over slowly?
 

Hey guys just inherited this prairie 360 from a buddies father. He said the crank was bent but after noticing the Engine brake was disconnected and all of the lights flashing I think there might be something going on in there.

The engine cranks but does so slowly as if something is holding it back. I found a bypass relay for the engine brake but have no clue and don't wanna spend unneccesary money if its not the problem. If the cover is off it spins fine. Any suggestions? New to the 4x4 machines.

Anyone?
