1. Place the starter anchor on two V-shaped supports and measure the radial runout of the collector with an arrow-type indicator. Nominal value: 0.05 mm Limit value: 0.1...

Checking for breaks in the stator winding
If the circuit between the brushes is closed, then the excitation winding is in good condition.

Checking for short circuit of stator winding to ground
Using an ohmmeter, measure the resistance between the brush and the pole (stator housing). If the resistance tends to infinity, then there is no short circuit of the...

Checking the brush holder
Using an ohmmeter, measure the resistance between the brush holder plate and the brush holder as shown in the figure If the resistance tends to infinity, then the brush...

Checking the overrunning clutch
1. Hold the clutch housing with your hand, check the ease of rotation of the drive gear clockwise and the impossibility of rotation counterclockwise. 2. Make sure that...

Checking the brushes
1. Check the cleanliness of the brush contact surface with the commutator and also measure the length of the brushes. Brush length limit: Wear limit line. 2. If...

Checking the armature winding
1. Install the starter anchor in the trawler (device for detecting short-circuited turns in starter and generator windings). 2. While slowly turning the anchor in the...

Checking for breaks in the armature winding
Using an ohmmeter, measure the resistance between the collector lamellas. If the resistance is low (the circuit is closed), then the armature winding is in good...
