Checking the starter in the full braking

On the drive gear starter put on the jig with the lever 2, connected to a dynamometer, and serves to measure torque. At Test the starter switch to the 4-5 with no more to avoid overheating and damage. The braking torque is determined by the product of the length of the lever in meters on the reading dynamometer in kilograms. In serviceable starter with a voltage at the terminals of 12V and a current load is not more than 50A torque must be not less than 1.6 kgcm. If the test is cranking the armature shaft, fix or replace the freewheel Drive starter. If the power supply current above 500 A, and the braking torque below 1.6 kgf-m, is a malfunction of the armature winding and field winding. If the value of the braking torque and the power consumption below the current starter normal (the normal voltage at the terminals of the starter), it indicates of bad xcontacts inside the starter or a weak spring tension of brushes. If the value of the braking torque and the current consumed by the starter, the following normal (at reduced voltage at the terminals of the starter), it indicates of bad xcontacts in the wires or faulty battery.
