Checking the starter on the lack of closure of winding to ground

To verify the absence of the internal circuit of starter circuit to ground do the following: - Lift the collector of the bare "mass" brush; - Disconnect the output of the shunt coil of uninsulated brush holder; - Disconnect the output winding of the pulling starter relay; - Move to the conclusion of the excitation winding and the voltage of the starter housing (A test light) from the battery or mains. If the thread tube was heated, it will point to the availability, short circuit inside chain starter. To verify the absence of the field winding circuit to make a lot of the following: - Disconnect the output winding of the traction relay; - Lift the bare brush; - Disconnect the output of the shunt coil of uninsulated brush holder; - Loosen the screws on the isolated brush holders and remove them from the brush; - Move the voltage to the conclusion that the field winding and the starter housing. Tungsten filament lamps control indicates the presence of short-circuit winding. Closure of the absence of isolated brush holders to spend a lot of under the same conditions as in the previous test. However, the voltage is supplied the isolated brush holder and the mass. To verify the absence of fault on the armature winding, a lot of lift non-isolated and isolated brush, move the voltage to lammelyam reservoir and the housing starter. If the test lamp filament was heated, this indicates the presence of short-circuit armature winding to ground. Armature winding interturn short circuits on the check at a special booth. Anchor 1 (Fig. 207) lay the ball on the stand, and a transformer turn on the stand in the AC line voltage of 120 V or 220 V. Then the iron armature axis, apply a thin steel plate and slowly turning the anchor, and holding the plate from turning together with the anchor watch behind the plate. In the presence of interturn closure plate begins to vibrate and drawn the appropriate anchor slot. To check the circuit armature winding or collector lammeley on the weight of the anchor test the summing up to it 220 V AC current series with the lamp. One pole current source is applied to any lammeli collector, and another - to the shaft anchor. If the lamp filament become heated, it points to the closure of the winding (Or parts of the reservoir) to ground. If there is damage to the anchor replace it. Москвич-412
