6300/6310 Transformer Test Procedure
1. Make sure that transformer wire connections (CON1) to the drive board are secured. Turn unit on.
2. Put multimeter to the AC voltage setting. Insert meter probes into the transformer primary (red)
wires as shown. Normal reading: 110V. This shows that there is power to the transformer.
3. Test transformer output by probing on secondary (output) wires: black and black, white and white,
orange and orange, yellow and yellow.
6300/6310 Transformer Test Results
1. If there is no voltage across the primary (red) wires, inspect F1 fuse on the drive board and power
to the drive board.
2. If there is voltage across primary wires but none across secondary wires, the transformer is bad.
Replace it.
