IF voltage selector plug matches voltage, go to step
2B. IF not, power down, replace FC1 & FC2 fuses, &
switch plug to proper voltage.
Inspect transformer wiring
Inspect transformer wiring, ensuring the insulation
on the wiring is not damaged. IF damaged replace
transformer (pg. 25). IF OK go to 2C.
Verify voltage selector plug
With power off, remove the P3 & P4 plugs. On the P3 plug measure resistance between the
orange & yellow wires for 1.9 – 2.9 Ohms, then do the same between the black and brown
wires. IF resistance is out-of-range, replace transformer (pg. 25). IF OK and problem still
persists, contact technical support: (908) 355.7995.
