Check the starter is recommended that a special control
test bench. Starter experience at idle and in full
braking and traction have included the starter relay. The source of power
starter in the tests can serve as a battery or low voltage
Checking the starter idle
Instruments and appliances for testing: a control booth, or (in the absence of
stand) gripe, an ammeter with a shunt, voltmeter, tachometer. The electrical circuit
enable the starter to check is shown in Fig. 206. To test the
idle starter set for a special stand or hold in a vise.
The used battery should be 7 polyostyu charged.
The connecting wires to the battery to the shunt ammeter 6 and 3 should be the starter
have a cross section of not less than 16 mm2.
When the voltage at terminal 12 defective starter should consume a current of
no more than 85 A, and the speed of the armature must be at least 5000 1 \ min.
Increased consumption of current, low speed, and noise
while the evidence of electrical and mechanical faults
starter as a result of incorrect assembly, circuit armature winding on the "mass"
or a circuit between the turns. Low power supply current and reduced the frequency of
rotation of the crankshaft of the engine at normal voltage at the terminals
Starter indicate poor xcontact in wiring connections, or weak
spring clip brushes.
