ENERSYS SCR Transformer Type Battery Charger D3E2

Return all replaced components to your service center.

The following sections explain how to replace each component. After replacing a component, be sure to:

1. Reconnect all leads exactly as they were removed,

2. Replace any heat-shrink tubing if any old tubing was removed,

Please follow these steps before removing or replacing any component:

Please follow these steps before testing the diode:

You will be testing the diode to see if it is shorted.

1. Disconnect the three phase input wires to the SCR/Diode Blocks.

2. Use an analog meter set to its X1 scale, or use a DVM set to its diode scale.

3. Connect the meter's negative lead to the input connection of the SCR/Diode Block.

4. Connect the meter's positive lead to the - bussbar.

CONTROL TRANSFORMER (IF AVAILABLE)

Please follow these steps before testing the control transformer:

You will be testing the wiring of the control transformer for continuity.

1. Lugs 1 through 5 are located at the front of the control transformer, with lug 1 at the top.

2. Lugs 6 through 10 are located in the back, with lug 10 at the top.

3. Measure across the lugs specified in the ID Board.

4 If what you measure does not correspond with what is listed in the table, replace the control transformer.;

Please follow these steps before testing the fuses:

You will be testing each fuse to see whether there is continuity across it.

1. Using an ohmmeter, set to its x1 scale, test each fuse.

2. If a fuse tests as an open circuit (infinity), replace it.

3. If there is continuity across the fuse (less than 1 ohm), it is working properly.
