TEST PROCEDURE

1. Turn the engine off.
2. Perform the

Case Cover Removal

proce-

dure.

NOTE:

It is necessary to remove the fuel cap in

order to take the case cover off the machine.

Be sure the fuel cap is ON when discharging

the chopper module capacitors.
3. Locate the chopper module and capacitor

assembly on the inner machine baffle. See

Figure F.2 and the Wiring Diagram.

NEVER USE A SHORTING STRAP TO DIS-

CHARGE CAPACITORS

. If the Lincoln rec-

ommended resistor, or an equivalent resistor is

used, the capacitors can be discharged by

holding the resistor with insulated pliers and

using the resistor terminals to bridge Chopper

Module terminals B1 to B2, and B4 to B5. DO

NOT TOUCH THE TERMINALS OR METAL

PARTS OF THE PLIERS WITH YOUR BARE

HANDS. Hold the resistor in place for about 10

seconds.

If another type of resistor is used, jumper

leads may need to be attached to the resis-

tor. The leads can then be used to connect

terminals B1 to B2, and B4 to B5.

4. Using the volt/ohmmeter, check the voltage

across B1 and B2, then B4 and B5. It

should be zero volts in both cases.
