ENERSYS SCR Transformer Type Battery Charger GTX

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

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

Sign off on the AC and DC Fuses Test
