Schematics
Champion places an electrical schematic in the control cabinet of every machine before it is
shipped. Schematics are included at the back of this manual as well. Be aware that these schemat-
ics include options that may not apply to your machine. Options are enclosed in dashed lines with
the words (IF USED) next to them on the schematic. Disregard any options that appear on the
schematics which are not a part of your machine.
Electrical Circuit Tests
Use a clip-on AC current tester to check the motors and electric heaters.
Use a VOM to test line voltages and the 120VAC control circuit.
NOTE:
DO NOT USE CHASSIS GROUND WHEN PERFORMING VOLTAGE CHECKS.
Doing so will result in false and inaccurate readings.
PERFORM VOLTAGE CHECKS BY READING FROM THE HOT SIDE OF THE
LINE AND NEUTRAL (any #2 or white wire).
Tools
Most repairs can be made with: Standard set of hand tools, Volt/Ohm Meter (VOM), and
Clip-on AC current tester. Special tools necessary to perform a repair are noted in the specific
