3. Check for 42 to 64 Vdc between the main wire harness P41 connector, pin 1, ( Figure 75 ) and the main wire harness
P04 connector, pin B ( Figure 72 ) .
4. Rotate the key switch to the O
FF
position. Connect the main wire harness P41 connector ( Figure 75 ).
Pass Voltage reading was good. Go to Returning the Equipment to Service (page 19) and follow the
steps listed.
Fail Voltage reading was not good. Go to step 8.
Step 8: Use a multimeter to check for 42 to 64 Vdc at the key switch.
1. Rotate the key switch to the S

position and hold it until the InfoCenter LCD display lights up, then release the
key switch to the R
UN
position.
2. Check for 42 to 64 Vdc between the main wire harness P13 connector, pin E ( Figure 73 ), and the main wire harness
P04 connector, pin B ( Figure 72 ).
3. Rotate the key switch to the O
FF
position, and then connect the main wire harness P13 connector ( Figure 73 ).
Pass Voltage reading was good. Go to Returning the Equipment to Service (page 19) and follow the
steps listed.
