capoman, what was wrong with using the factory terminal block?
It has the thermal overload Klixon and PTC for starting. Make sure the compressor has a ground wire. If the motor is burnt it will short-circuit Line to case and you will get electrocuted. Be safe.
When it ran for 30-40 seconds, either the Klixon tripped from overheating or the motor has no oil and seized. The datasheet says mineral oil 210cc.
