CAUTION

Do not use a battery or test lamp

test.

Reverse battery connection

instantly .

NOTE

to make a continuity

will burn out diodes

1.

3.

On ohmmeters that use one 1 1/2-volt dry cell, low

resistance readings will be approximately 20 to 30 ohms.

On ohmmeters that use a 3-volt dry cell, low resistance

readings will be approximately 10 to 15 ohms.

Positive rectifier (1) has a coating of epoxy for in-

sulation.

Check resistance of positive rectifier (1). Touch positive test probe of

multimeter to checkpoint one (2) and negative test probe to each of three

rectifiers (3, 4, and 5). Ohmmeter must show low resistance when negative

test probe is touched to each rectifier.

Check resistance of negative rectifier (6). Touch negative test probe of

multimeter to checkpoint two (7) and positive test probe to each of three

rectifiers (8, 9, and 10). Ohmmeter must show low resistance when positive

test probe is touched to each rectifier.

If rectifiers (3, 4, 5, 8, 9, and 10) do not have low resistance, get new ones.
