Check that screws (4) are not bent or broken and that they have no damaged

threads. If screws are damaged, get new ones.

Using multimeter, check that rotor (5) has no grounds. Touch one test

probe to rotor shaft (6) and touch other test probe to one slipring (7)

and check that ohmmeter reading is over 10, 000 ohms. If readings is not

over 10,000 ohms, get a new generator.

Do step 4 again for other slipring (7).

Using multimeter, check resistance of two sliprings (7). Touch ohmmeter

test probes to two sliprings at same time and check that resistance is be-

tween 7.0 and 7.8 ohms. If resistance is not within given limits, generator
