6. Secure the starter in a vise.
7. Connect the starter motor to the battery as shown in the diagram below and check that the electric motor starts and continues to rotate.
8. If, at a battery voltage of 11.5 V, the current and speed of the electric motor correspond to the nominal ones, the starter is working properly.
