Not sure which circuit you mean by "half moon relay" and really not sure 
why there is any "grease" involved in an electrical circuit.  So please 
attach a simple drawing of the circuit, including the battery, switches 
and motor. It sounds like you have a dead-short of some sort in the 
circuit, which we should be able to determine from the diagram you send.
