ENERSYS SCR Transformer Type Battery Charger D3G

Disconnect the battery and AC power before testing the fuses.

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

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

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

To test if the LEDs are working, turn AC power off then back on.

When the power is turned on, all the LEDs should blink.

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

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

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

Enter the lugs specified in the ID Board.

Enter the measurement across the lugs.

Does the measurement correspond with what is listed in the table?

Replace the control transformer if the measurement does not correspond?
