Please follow these steps before testing the Transformer:

Connect the charger to AC power.

You will be testing the transformer's windings (with a good quality meter) to check the transformer's voltages.

Your measurements should be within 10% of what is listed on the nameplate.

Second Transformer Test (120V Test)

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.
