Label all wires and make a reference drawing before disconnecting any wires.
The wire numbers referred to below are typical for an M5G machine and WILL NOT hold true for all others.
*Wire numbers may change on machines made before approximately 1988.

TROUBLESHOOTING PROCEDURE:
1. Disconnect wire E03 and E04 at the recctifiers and read the voltage at MTA25-1. If it reads 16VAC, the transformer is probably still good, although possibly weak. If there is no voltage, replace the transformer.

2. Read the voltage at MTA25-2 and MTA25-3. There should be voltage here.

3. Disconnect wires E07 and E08 from the extract rectifier and read and record the resistance value. It should be 2.5 to 3 ohms. Also read each lead to the frame of the clutch; these should read infinity.

4. Remove wires E05 and E06 from the wash rectifier and read the and record the resistance. It should be 2.5 to 3 ohms. Also read each lead to the frame of the clutch; these should read infinity.

7. Replace both rectifiers. They are relatively inexpensive and may solve the problem.

AFTER REPLACING THE FAULTY PART(S), READ VOLTAGES AT THE CONNECTING WIRES.
1. There should be 16VAC at MTA25-2. The rectifier should be 12VDC.
2. The rectifier should be 12VDC. The 12VDC should change only slightly when the wash clutch is connected.

NOTE: The 10 amp fuse is no longer used in production and is not necessary for the circuit. However, eliminating the fuse will solve the cause of the burnt fuse.
