Transformer Voltage Test

To test the Transformer it must be removed from the Electrical Compartment by removing the Electrical
Chassis as described on Page 6-54. Once removed and on a bench proceed as follows.
1. Pull the two wires off the transformer terminals marked COLL and ION (Refer to Figure 6-55-1).
2. On the plug marked RELAY, place a jumper wire between the two terminals to connect the two
orange wires.
3. On the plug marked INPUT, connect a 120 volt power cord with alligator clips to power up the
Transformer.
4. Set selector switch on volt meter to the highest DCV scale.
5. Place probe or clip labeled "common" from the high volt meter against the terminal marked GROUND.
6. While holding down the Plunger Safety Switch place the high voltage probe against the ION
connection point. Voltage should be 9,000 to 11,000 DC.
7. While holding down the Plunger Safety Switch place the high voltage probe against the COL
connection point. Voltage should be 4,700 to 5,500 DC.
8. If either of the voltages is below the required range, it indicates that the Transformer is defective and
must be replaced. Refer to the Parts Chapter of this manual.
